Neuro: Neuropathic Pain: Free MSRA Podcast

🎧 FREE MSRA PODCAST – Neuropathic Pain: High-Yield Recognition & Management EssentialsStruggling to get your head around neuropathic pain? In this Deep Dive, we strip it back to the must-know facts for the MSRA: core definitions, classic symptoms, and what NICE actually recommends for treatment.📝 Key Learning Points📌 Definition• Chronic pain originating from damage or dysfunction within the nervous system• IASP: “Pain caused by a lesion or disease of the somatosensory system”📌 Typical Descriptions• Burning, electric shock, shooting, stabbing, tingling, numbness• Look for words like “pins & needles”, “shooting pain”, “allodynia” (pain from light touch)📌 Common Causes• Peripheral: Diabetic neuropathy, postherpetic neuralgia, trigeminal neuralgia, radiculopathy, alcohol neuropathy, trauma• Central: Post-stroke pain, multiple sclerosis, spinal cord injury• Chemotherapy (can be both)📌 Risk Factors• Diabetes, trauma, infections (e.g. shingles), autoimmune diseases, neurotoxic drugs (e.g. chemo), older age📌 Pathophysiology• Nerves become hyper-excitable• Abnormal pain signalling & altered pain processing in both peripheral and central nervous systems• Maladaptive rewiring leads to chronicity📌 Key Clinical Features• Pain quality: Burning, shooting, tingling, electric• Sensory changes: Allodynia, hyperalgesia, paraesthesia• Distribution: Often follows nerve/root pattern• Functional impact: Sleep, mood, daily life often impaired📌 Differential Diagnosis• Nociceptive pain (tissue injury: ache/throb)• Musculoskeletal pain (joints, muscle)• Psychogenic pain (psychological drivers)• Red flags: Always clarify quality & triggers!📌 Epidemiology• Affects 7–10% of UK adults• More common with age and in chronic conditions (e.g. diabetes: 16–26% have painful neuropathy)📌 Investigation• History + neuro exam (pain description is key!)• Nerve conduction studies, MRI for compression/structural causes• Bloods for diabetes, B12, thyroid if relevant📌 Management (NICE CG173, 2013)First-line (except trigeminal neuralgia):1️⃣ Amitriptyline2️⃣ Duloxetine3️⃣ Gabapentin4️⃣ Pregabalin→ Try sequentially; switch if not tolerated/effective• Rescue: Short-term tramadol for acute flares• Localised: Topical capsaicin cream• Non-drug: CBT, physio, pain team referral for resistant cases⚠️ Avoid starting (unless pain specialist involved):Cannabis extract, high-strength capsaicin patches, lacosamide, lamotrigine, oxcarbazepine, tapiramate, long-term tramadol, venlafaxine, morphine/strong opioids📌 Prognosis & Complications• Variable: Some resolve, many are chronic• Key impact: Reduced quality of life, sleep disturbance, depression/anxiety, disability• Multidisciplinary care is essential📎 More MSRA Neuropathic Pain Resources:📝 Revision Notes: https://www.passthemsra.com/topic/neuropathic-pain-revision-notes/🧠 Flashcards: https://www.passthemsra.com/topic/neuropathic-pain-flashcards/💬 Accordion Q&A: https://www.passthemsra.com/topic/neuropathic-pain-accordion-qa-notes/🚀 Rapid Quiz: https://www.passthemsra.com/topic/neuropathic-pain-rapid-quiz/🧪 Quiz Bank: https://www.passthemsra.com/quizzes/neuropathic-pain/🎓 Neurology MSRA Course: https://www.passthemsra.com/courses/neurology-for-the-msra/#MSRA #NeuropathicPain #MSRARevision #MSRAFlashcards #MSRAQuiz #MSRAAccordions #Neurology #ChronicPain #PassTheMSRA
