- SlidesComplex Regional Pain Syndrome (CRPS)Pain that is disproportionate to the injury and to the healing phase, plus autonomic and trophic change — colour, temperature, swelling, sweating, skin, hair, nails — in a limb after injury, surgery, fracture or immobilisation. The diagnosis is clinical, against the Budapest criteria. The management is early, calm, graded movement — and the commonest way it gets worse is being immobilised and frightened.
- SlidesInfection / Malignancy — the non-mechanical pain that doesn't settleConstant, non-mechanical, progressive pain that does not respond to rest or to appropriate treatment, in someone with a reason to be at risk. The evidence does not support screening by checklist — most individual red flags perform poorly. What it supports is noticing when flags cluster, when the clinical course is wrong, and when a prior cancer history changes the whole picture.
- SlidesPeripheral Nerve Entrapments (General)Burning, tingling or numbness along a named nerve, driven by sustained posture, compression, repetitive load or neural tension, and eased by unloading. The reasoning question is not 'which nerve' but 'which level' — peripheral nerve, root, plexus, or something broader — and the honest caveat is that symptoms routinely spread beyond the textbook map, so a symptom outside the territory does not clear the diagnosis.
- SlidesReferred (Visceral) PainDeep, poorly localised, non-mechanical pain that varies with meals, exertion, urination or the menstrual cycle rather than with movement — and does not change with anything you do to it. Your job is not to name the organ. It is to notice that the pain behaviour does not fit local musculoskeletal tissue, screen the systems, document it, and refer.
- SlidesVascular vs Neurogenic ClaudicationLeg symptoms that limit walking and settle with rest, in an older adult. The classic rule — sitting relieves it means neurogenic, standing still relieves it means vascular — is a genuinely useful starting point and a poor finishing point, because single symptoms are weak discriminators and the two conditions frequently coexist. The pattern to hold is: which constellation, and have I checked the vessels?
