Interventional pain management is a specialised approach that uses targeted procedures such as diagnostic nerve blocks, joint injections, epidural injections, or radiofrequency treatment to help manage selected pain conditions. It is not simply “an injection for pain.” The aim is to identify the likely pain source, reduce symptoms when appropriate, improve movement and daily function, and support rehabilitation.
For people living with persistent back pain, neck pain, joint pain, sciatica, nerve pain, or pain after injury or surgery, interventional pain management in Nepal may be considered after a careful medical assessment. The right treatment depends on the cause of pain, the affected body part, examination findings, imaging where needed, previous treatment, and overall health.
At Karuna City Clinic, the approach begins with consultation, diagnosis, and a clear care plan. The clinic provides orthopaedic consultation, diagnostic imaging support, X-ray and ultrasound services, minor procedures, and referral coordination when a more advanced pain intervention is clinically appropriate.
What Is Interventional Pain Management?
Interventional pain management uses minimally invasive procedures to diagnose or treat pain that has not improved enough with basic care alone. It may include targeted injections, nerve blocks, joint injections, radiofrequency ablation, or other pain procedures performed by qualified specialists.
These procedures are not suitable for every type of pain. A good plan combines accurate diagnosis, exercise or rehabilitation, appropriate medicines when needed, lifestyle guidance, and psychological support where pain affects sleep, mood, work, or daily functioning.
What Is the Difference Between Pain Management and Interventional Pain Management?
Pain management is the broad process of assessing pain and helping a person function better. It can include education, medicines, exercise, physiotherapy, sleep support, counselling, treatment of the underlying condition, and specialist referral.
Interventional pain management is one part of pain care. It uses procedures that target a suspected pain generator, such as an irritated nerve root, inflamed joint, facet joint, sacroiliac joint, or peripheral nerve.
| Pain Management | Interventional Pain Management |
|---|---|
| A broad, multimodal approach to pain relief and improved function | A procedural branch of pain care |
| May include medicines, exercise, rehabilitation and counselling | May include nerve blocks, epidural injections, joint injections or radiofrequency procedures |
| Often appropriate from the first consultation onward | Usually considered after a diagnosis-focused assessment |
| Focuses on pain intensity, movement, sleep, mood and quality of life | Focuses on a specific pain pathway or anatomical source |
| May be managed by primary-care and specialty teams | Requires appropriately trained clinicians and safe procedural facilities |
The important point is that procedures do not replace comprehensive care. A successful injection may create a window of reduced pain that allows a patient to move more comfortably, participate in rehabilitation, sleep better, and return to everyday activity.
When Does Pain Become Chronic?
Pain is generally considered chronic when it persists or recurs for more than three months. It may continue after an injury has healed, occur with an ongoing medical condition, or become more complex because the nervous system remains sensitised.
Chronic pain is not “just in the mind.” Pain is a real sensory and emotional experience influenced by the body, nervous system, sleep, stress, previous injury, activity level, and social circumstances.
For this reason, a pain management clinic in Nepal should assess more than the location of pain. It should also assess how pain affects work, walking, sleep, mood, caregiving, exercise, and independence.
Which Conditions May Benefit From Interventional Pain Management?
Interventional procedures may be considered for selected patients after clinical assessment. Common examples include:
- Persistent neck pain linked to facet joints or arthritis
- Chronic lower back pain with a suspected facet-joint source
- Sciatica or radiating leg pain caused by nerve-root irritation
- Sacroiliac joint pain around the lower back, buttock, or pelvis
- Shoulder, hip, knee, or other joint pain when a targeted injection is appropriate
- Myofascial pain involving tight, tender muscles or trigger points
- Peripheral nerve pain or nerve entrapment
- Pain after surgery, injury, or trauma
- Selected cancer-related pain conditions under specialist care
A pain procedure should always be linked to a working diagnosis. For example, an epidural injection is not a general treatment for every type of low back pain. It may be considered in specific cases, such as severe sciatica, where clinical findings support nerve-root irritation.
Similarly, radiofrequency ablation is not used simply because someone has back pain. It is generally considered only after appropriate assessment and, in selected cases, a positive diagnostic nerve block.
What Happens During a Pain Assessment?
A good pain assessment is structured. It should answer two important questions:
- What may be causing the pain?
- What is the safest and most useful next step?
At a consultation, the clinician may ask about:
- When the pain started and whether it began after injury, surgery, illness, or activity
- The exact location of pain and whether it spreads to the arm, leg, groin, shoulder, or chest
- Pain quality: aching, burning, electric-shock-like, stabbing, numbness, heaviness, or pressure
- Severity and what makes it worse or better
- Weakness, tingling, numbness, balance difficulty, stiffness, or swelling
- Sleep disturbance, work limitations, walking tolerance, and emotional impact
- Previous medicines, physiotherapy, injections, scans, surgery, or home remedies
- Medical conditions such as diabetes, blood-thinner use, infection risk, osteoporosis, kidney disease, or pregnancy
The examination may include posture, walking, range of motion, muscle strength, sensation, reflexes, joint testing, and signs of inflammation.
Imaging is not required for every painful condition. However, X-ray, ultrasound, MRI, CT, or laboratory tests may be useful when they are likely to change treatment decisions or help rule out a serious cause.
Karuna City Clinic offers orthopaedic consultation services for musculoskeletal pain involving bones, joints, muscles, ligaments, tendons, and nerves. The clinic also lists X-ray, ultrasound, pathology, and other diagnostic and imaging services that may support a diagnosis-focused plan.
What Are Common Interventional Pain Procedures?
The procedure selected depends on the diagnosis. The options below are examples of interventions commonly used in pain medicine. They should only be performed after proper assessment and by appropriately trained clinicians.
| Procedure | Main Purpose | When It May Be Considered |
| Diagnostic nerve block | Helps identify whether a specific nerve is contributing to pain | Suspected facet-joint or peripheral nerve pain |
| Epidural injection | Delivers medicine around irritated spinal nerve roots | Selected acute or severe sciatica and radicular pain |
| Facet joint injection | Targets small spinal joints that may be causing local pain | Suspected facet-mediated neck or back pain |
| Sacroiliac joint injection | Targets the joint between the spine and pelvis | Pain around the lower back, buttock, or pelvis |
| Trigger-point injection | Helps manage painful muscle knots or myofascial pain | Localised muscle pain with trigger points |
| Peripheral nerve block | Temporarily interrupts pain signals from a selected nerve | Certain nerve-related pain conditions |
| Radiofrequency ablation | Uses heat-based energy to interrupt targeted pain signals | Selected long-term facet or joint-related pain after diagnostic confirmation |
| Neuromodulation | Uses electrical stimulation to alter pain signalling | Selected complex chronic pain conditions after specialist assessment |
Not every clinic provides every procedure. At Karuna City Clinic, patients can begin with evaluation, orthopaedic assessment, and diagnostic support. Availability of specific image-guided spinal or nerve procedures, or the need for referral to a specialist centre, should be confirmed during consultation.
What Is an Intervention in Pain Management?
An intervention in pain management is a targeted treatment intended to reduce pain, improve function, or clarify the source of symptoms.
It may be diagnostic, therapeutic, or both.
For example, a nerve block can help determine whether a specific nerve is causing pain. If a patient experiences meaningful temporary relief after the block, it may help the specialist decide whether a longer-lasting treatment such as radiofrequency ablation is appropriate.
An intervention is not necessarily surgery. Many procedures are minimally invasive and use a fine needle, local anaesthetic, imaging guidance, or a short recovery period. However, “minimally invasive” does not mean risk-free. Every procedure should involve informed consent, explanation of alternatives, and a discussion of expected benefit and possible complications.
What Is the Most Common Intervention for Pain Relief?
There is no single “most common” intervention that is right for every patient. First-line care for many musculoskeletal pain conditions often includes education, staying as active as safely possible, graded exercise, rehabilitation, sleep support, and appropriate medicines.
Within interventional pain medicine, injections are among the more common procedures. These may include joint injections, epidural injections, trigger-point injections, or diagnostic nerve blocks. The best option depends on the diagnosis rather than the pain score alone.
A patient with non-specific lower back pain may benefit more from exercise and rehabilitation than an injection. A patient with severe sciatica caused by nerve-root inflammation may need a different plan. A patient with chronic facet-joint pain may require diagnostic confirmation before radiofrequency treatment is considered.
Benefits of a Diagnosis First Pain Plan
A well-planned pain strategy may help patients:
- Reduce pain enough to return to rehabilitation or normal activity
- Improve walking, sitting, sleep, work, and daily functioning
- Avoid repeated use of unnecessary medicines
- Clarify the source of pain before a longer-term procedure
- Make a more informed decision about surgery or non-surgical care
- Reduce fear around movement by creating a gradual recovery plan
- Monitor outcomes using pain scores, function, and quality-of-life measures
The best result is not always “zero pain immediately.” Often, a meaningful outcome is being able to walk farther, sleep through the night, sit comfortably at work, care for family, exercise safely, or reduce reliance on pain medicines.
What Are the Limits of Interventional Pain Management?
Pain procedures are not cures for every condition. Some people do not respond, while others experience partial or temporary relief. Benefit can vary according to the underlying diagnosis, duration of symptoms, nerve sensitivity, activity level, sleep, medical conditions, and whether the patient can participate in rehabilitation.
A procedure should not be used only because pain has lasted a long time. It should have a clear clinical purpose.
For chronic non-specific lower back pain without sciatica, repeated spinal injections are not routinely recommended. In selected people with suspected facet-joint pain, radiofrequency treatment may be considered after conservative care has not worked and a diagnostic block indicates that the targeted nerves are involved.
This is why an individual assessment matters. It helps avoid unnecessary procedures and directs treatment toward the most likely source of pain.
Are Pain Procedures Safe?
Pain interventions can be safe when they are medically appropriate, performed by trained clinicians, and carried out in a proper clinical setting. However, every procedure has potential risks.
Possible risks may include:
- Temporary soreness or flare of pain
- Bruising or bleeding
- Infection
- Allergic reaction to medicines or contrast material
- Dizziness or fainting
- Temporary numbness or weakness
- Steroid-related effects, including short-term blood-sugar rise in some people
- Rare nerve injury or serious complications, particularly with spinal procedures
Tell the clinician if you have diabetes, take blood-thinning medicines, have a bleeding disorder, are pregnant, have fever or active infection, have an allergy, or have recently received another injection.
For many spine related procedures, imaging guidance and sterile techniques are important safety measures. The clinician should clearly explain why the procedure is recommended, what it is expected to achieve, what alternatives are available, and when to seek urgent help after treatment.
What Are the 4 P’s of Pain Management?
There is no single universally accepted “4 P’s” framework used by every pain service. A practical patient centred version includes:
- Pain assessment – understanding the cause, severity, pattern, and functional impact.
- Pharmacological treatment – using medicines carefully when they are appropriate.
- Physical rehabilitation – movement, exercise, physiotherapy, posture, pacing, and strengthening.
- Psychological support – addressing sleep, fear of movement, stress, coping, and the emotional burden of long-term pain.
Interventional procedures may be added when there is a clear clinical indication. They should support—not replace—the four areas above.
What Are the 5 P’s of Pain Assessment?
The “5 P’s” can mean different things in different clinical settings, so it is important not to use one list as a diagnosis by itself.
For a general pain history, clinicians often use a structured approach similar to PQRST:
- Provocation or Palliation: What makes the pain worse or better?
- Quality: Is it burning, sharp, aching, electric, tight, or throbbing?
- Region or Radiation: Where is it, and does it travel anywhere?
- Severity: How intense is it and how much does it limit function?
- Timing: When did it start, how long does it last, and is it constant or intermittent?
In emergency or circulation assessment, a different “5 P’s” list may be used: pain, pallor, pulse, paraesthesia, and paralysis. That version is especially relevant when there may be impaired blood flow or nerve function in a limb.
What Are the 7 Types of Pain?
There is no single universal list of exactly seven pain types. Pain is commonly classified by duration, mechanism, and location. A practical way to describe seven common categories is:
- Acute pain – short-term pain related to injury, illness, surgery, or inflammation.
- Chronic pain – pain lasting or recurring for more than three months.
- Somatic nociceptive pain – pain from muscles, bones, joints, skin, or soft tissues.
- Visceral nociceptive pain – pain from internal organs.
- Neuropathic pain – pain caused by nerve injury or disease, often burning, tingling, or electric-shock-like.
- Nociplastic pain – pain linked to altered pain processing without clear ongoing tissue injury.
- Mixed pain – pain involving more than one mechanism, such as arthritis with nerve irritation.
These categories can overlap. A person may have chronic pain that is both nociceptive and neuropathic.
When Should You See a Doctor Urgently?
Do not wait for a routine pain consultation if pain appears with warning signs such as:
- New weakness in an arm or leg
- Loss of bladder or bowel control
- Numbness around the groin or inner thighs
- Sudden severe headache, chest pain, or abdominal pain
- Fever, unexplained weight loss, or night sweats with back pain
- Pain after a major fall, accident, or trauma
- A history of cancer with new severe bone or back pain
- Severe pain with swelling, redness, coldness, or colour change in a limb
- Pain during pregnancy with bleeding, fainting, or severe abdominal symptoms

Interventional Pain Management at Karuna City Clinic
Karuna City Clinic follows a multidisciplinary model that includes orthopaedics, radiology, general medicine, gynaecology, surgery, diagnostics, laboratory services, pharmacy support, and minor procedure pathways.
For persistent musculoskeletal pain, the first step is usually consultation with the relevant clinician. The clinic’s orthopaedic team can assess bone, joint, muscle, tendon, ligament, nerve, back, knee, shoulder, hip, and injury-related concerns.
The clinic also lists consultant radiologists through its radiology service, which can support appropriate diagnostic decision-making. When a pain intervention is needed, the care team can discuss whether it is suitable, whether it can be arranged locally, and whether specialist referral is required.
Before booking, keep previous prescriptions, scan reports, X-rays, MRI or CT reports, laboratory reports, and details of past injections or surgeries ready. This helps the clinician avoid unnecessary repeat tests and build a clearer plan.

Frequently Asked Questions
What’s the difference between pain management and interventional pain management?
Pain management includes medicines, rehabilitation, exercise, sleep support, counselling, and treatment of the underlying condition. Interventional pain management uses targeted procedures such as nerve blocks, joint injections, epidural injections, or radiofrequency treatment for selected diagnoses.
What are the 4 P’s of pain management?
A practical 4 P’s framework includes pain assessment, pharmacological treatment, physical rehabilitation, and psychological support. Interventional procedures may be added when clinically appropriate.
What is the intervention of pain management?
An intervention is a targeted diagnostic or therapeutic procedure used to identify or reduce pain from a specific structure or nerve pathway. Examples include nerve blocks, joint injections, epidural injections, trigger-point injections, and radiofrequency procedures.
What is the most common intervention for pain relief?
There is no one best intervention for everyone. For many people, exercise-based rehabilitation and education are important first steps. In interventional practice, injections such as joint injections, epidural injections, or diagnostic nerve blocks are commonly used when the diagnosis supports them.
What are the 5 P’s of pain assessment?
A practical pain-history framework includes provocation or palliation, quality, region or radiation, severity, and timing. In some emergency settings, the 5 P’s may mean pain, pallor, pulse, paraesthesia, and paralysis.
What are the 7 types of pain?
Pain may be described as acute, chronic, somatic nociceptive, visceral nociceptive, neuropathic, nociplastic, or mixed. These categories can overlap and should be assessed by a clinician.
The Bottom Line
Interventional pain management can be valuable for selected patients with persistent or complex pain, but it should always begin with accurate assessment. The right treatment is not the most invasive option it is the option that matches the diagnosis, improves function, and supports safe recovery.
Karuna City Clinic provides a starting point for orthopaedic assessment, diagnostic support, pain-related consultation, and coordinated care planning. For persistent back pain, joint pain, nerve pain, or pain affecting daily life, book a consultation to discuss the safest next step.
