"Why Does My Paralysed Limb Hurt?"

Your Questions Answered — Including Treatments Your Neurologist May Not Have Mentioned UNDERSTANDING THE BASICS Q I have paralysis. I was told I can't feel anything — so why do I have pain? This is one of the most common and most distressing questions patients ask. The short answer: paralysis and pain are controlled by different nerve pathways. You can lose the ability to move a limb — or even lose normal sensation — while a separate set of nerve fibres continues to send pain signals to the brain. In fact, up to 70% of people with conditions like stroke, spinal cord injury, or multiple sclerosis experience significant pain. It is not 'in your head.' It is a recognised medical condition with clear biological causes, and it has a name: central or neuropathic pain. KEY FACT Pain after paralysis is extremely common and completely real. The nervous system can misfire pain signals even when movement is lost — and this requires proper medical treatment, not simply acceptance. Q What causes pain in a paralysed limb? There is no single cause. In most patients, several mechanisms happen simultaneously. Here are the main contributors: Neuropathic Pain Damaged nerves send false 'danger' signals. Burning, electric, or stabbing sensations — even in limbs with no normal feeling. Central Sensitisation Brain and spinal cord become hypersensitive, amplifying every pain signal far beyond its actual source. Spasticity Paralysed muscles go into prolonged, involuntary spasm — causing deep aching, cramps, and joint stress. Musculoskeletal Disuse, abnormal posture, and joint contracture cause mechanical pain on top of nerve pain. Shoulder Pain Very common after stroke — caused by subluxation, spasticity, and rotator cuff injury from poor positioning. Bladder / Visceral In spinal cord injury, internal organ signals can be misread as surface pain (autonomic dysreflexia). After a stroke, spinal cord injury, multiple sclerosis, cerebral palsy, or traumatic brain injury — any combination of these mechanisms may be at play. A proper pain assessment will identify which are dominant in your case. THE UNDERTREATMENT PROBLEM Q My neurologist told me I have to 'learn to live with it.' Is that true? Unfortunately, this response — well-meaning as it may be — reflects a significant gap in how paralysis-related pain is managed. Neurology specialises in diagnosing and treating the cause of neurological conditions: the stroke, the spinal injury, the MS. Managing chronic pain after that diagnosis is a different subspecialty entirely. WHY THIS HAPPENS Many neurologists are not trained in interventional pain management. When they say 'bear it, ' they often mean 'I don't have a solution' — not 'no solution exists.' This is a crucial distinction every patient should understand. Research consistently shows that paralysis pain is undertreated globally. Patients go years — sometimes decades — in unnecessary pain because they were never referred to a pain specialist or rehabilitation physician. WHAT PATIENTS ARE TOLD 'This pain is part of your condition. There is nothing more we can do. You will have to learn to bear it.' THE REALITY Specialised pain management — including injections, botulinum toxin, nerve blocks, and targeted physical therapies — can significantly reduce paralysis pain for most patients. Q What kind of doctor should I actually see? You need a specialist who focuses on pain management and rehabilitation, not just the underlying neurological condition. Look for: • Pain Medicine Physician — specialist in chronic and neuropathic pain • Physiatrist / Rehabilitation Physician — expert in functional recovery and spasticity • Interventional Pain Specialist — performs nerve blocks and injection therapies • Neurorehabilitation team — physiotherapists and specialists working together Asking your neurologist for a referral to a pain specialist is not giving up — it is the medically correct next step when neurological pain is not controlled. AVAILABLE TREATMENTS Q What treatments are available for paralysis pain? The most important message: multiple effective treatments exist. The right approach depends on whether your pain is primarily from nerve damage, muscle spasm, spasticity, or a combination. A pain specialist will assess this and recommend accordingly. 1. Botulinum Toxin (Botox / Dysport) for Spasticity Q What is spasticity and how is it treated with Botulinum Toxin? Spasticity is a state of abnormal, continuous muscle tightness caused by damage to the upper motor neurones — the nerve pathways from the brain to the spinal cord. After stroke or spinal injury, these pathways lose their normal braking signals, causing muscles to contract involuntarily and remain in a painful, contracted state. Spastic muscles cause severe aching, cramping, joint pain, sleep disruption, and difficulty with daily activities. The tighter the muscles, the worse the pain — and the harder physiotherapy becomes. HOW BOTULINUM TOXIN WORKS Botulinum toxin (Botox, Dysport, Xeomin) is injected directly into the overactive muscle. It blocks the chemical signal (acetylcholine) that instructs the muscle to contract, allowing it to relax. This reduces pain, improves posture, and makes physiotherapy significantly more effective. Effects typically last 3-4 months, after which the injection can be safely repeated. Botulinum toxin for spasticity is well-established, evidence-based, and recommended in international guidelines for stroke and spinal cord injury rehabilitation. It is not experimental — it is standard of care where available. 2. Nerve Block Injections Q What are nerve block injections and could they help me? A nerve block is an injection of a local anaesthetic (and sometimes a steroid or neurolytic agent) near a specific nerve or group of nerves. By temporarily or semi-permanently interrupting the nerve's ability to transmit pain signals, the injection breaks the cycle of chronic pain. Nerve blocks are particularly useful when pain is localised to a specific region — for example, shoulder pain after stroke, leg pain after spinal injury, or painful muscle spasm in a specific area. Common blocks used include: • Peripheral nerve blocks (targeting specific limb nerves) • Sympathetic nerve blocks (for burning, neuropathic pain) • Trigger point injections (for localised muscle pain and spasm) • Epidural or intrathecal injections (for spinal cord injury pain) Nerve blocks can also be diagnostic: if a block gives relief, it confirms the targeted nerve is contributing to your pain — guiding further long-term treatment decisions. 3. Dry Needling for Muscle Spasm Q What is dry needling and how is it different from acupuncture? Dry needling is a precise physical therapy technique where a thin needle is inserted directly into a trigger point — a tight, tender knot within a muscle that causes local and referred pain. In paralysis, spastic muscles are riddled with these trigger points. Unlike acupuncture, which is based on traditional meridian theory, dry needling is based on modern understanding of muscle physiology. The needle disrupts the abnormal electrical activity at the trigger point, causing the muscle to reset and relax — relieving both local and referred pain patterns. WHY EXPERTISE MATTERS ENORMOUSLY Dry needling in paralysed or spastic patients requires exceptional skill and anatomical knowledge. Muscles may be atrophied, positioned abnormally, or severely contracted. An experienced practitioner knows how to navigate these safely and effectively — delivering results that standard physiotherapy or medications cannot match. Expert Spotlight Dr Priya Rathi Specialist in Interventional Pain Management · Dry Needling & Musculoskeletal Pain Dr Priya Rathi is an expert in dry needling for muscle spasm and trigger point pain, including in patients with neurological conditions and paralysis. Her approach combines precise anatomical knowledge with a deep understanding of how spasticity and disuse alter muscle behaviour — making her treatments both safe and highly effective for this complex patient group. She is specially trained to work with post-stroke, cerebral palsy, and spinal cord injury patients where standard physiotherapy alone is insufficient. 4. Other Treatments to Explore A comprehensive pain specialist may also recommend: • Neuropathic medications — pregabalin, gabapentin, or amitriptyline target nerve pain specifically and are more effective than standard painkillers • TENS / Transcutaneous Electrical Nerve Stimulation — non-invasive electrical stimulation to modify pain signals • Intrathecal Baclofen Pump — pump-delivered muscle relaxant for severe, refractory spasticity • Spinal Cord Stimulation — implanted device that modulates pain pathways at the spinal level • Psychological pain therapies — cognitive behavioural therapy (CBT) for pain is evidence-based and should accompany physical treatments TAKING ACTION Q When should I seek a pain specialist? Seek a pain specialist if any of the following apply: • Your pain has persisted for more than 3 months • Standard medications (paracetamol, NSAIDs) are not helping • Pain is affecting your sleep, mood, or rehabilitation progress • You have visible muscle spasm, tightness, or contracture • You were told to 'just live with it' without being offered a referral WHAT TO SAY TO YOUR NEUROLOGIST 'I am experiencing significant pain that is affecting my quality of life and my ability to participate in rehabilitation. I would like a referral to a pain medicine specialist or physiatrist who can assess me for interventional treatments such as botulinum toxin, nerve blocks, or dry needling.' Q Will treating my pain interfere with my neurological treatment? Almost never — and the opposite is usually true. Uncontrolled pain increases stress hormones, disrupts sleep, causes depression, and reduces motivation to engage in physiotherapy. All of these are known to worsen neurological recovery outcomes. Treatments like botulinum toxin are actually standard components of stroke rehabilitation in many countries. Nerve blocks are procedural, not systemic, and do not interact with most neurological medications. Dry needling requires no drugs at all. A well-coordinated team — neurologist, pain physician, and physiotherapist — is not a contradiction. It is the gold standard of care for patients with paralysis-related pain.
