Complex regional pain syndromes (CRPS, reflex sympathetic dystrophy, causalgia) are painful disorders that develop after trauma affecting a limb with (I) or without (II) nerve injury. Clinical features are pain, impairment of motor function, swelling and autonomic abnormalities (changes in sweating and blood flow). Autonomic abnormalities. The maximal skin temperature difference between the affected and unaffected extremity that occurs during a controlled thermoregulation can be used as a diagnostic tool. SMP. Sympathetic outflow to the painful extremity was experimentally activated. The intensity as well as area of spontaneous pain and mechanical hyperalgesia increased considerably in patients that had been classified as having SMP by positive sympathetic blocks. A pathological interaction between sympathetic vasoconstrictor and afferent neurons within the affected skin is the likely explanation for SMP in CRPS patients. Motor abnormalities. Kinematic analysis of target reaching as well as grip force analysis showed a pathological sensorimotor integration located in the parietal cortex. Furthermore, MEG studies demonstrated a continuous inhibition of the primary motor cortex.Neurogenic inflammation. Some features of acute CRPS (vasodilatation, swelling, pain) indicate a localized inflammatory process. Transcutaneous electrical stimulation of nociceptive C-fibre provoked protein extravasation into the interstitial fluid (microdialysis) only in CRPS patients and not in controls.

Yes. The male platypus has a venomous barbed spur concealed on the underside of its left hind limb. While both male and female Platypus are born with ankle spurs, only the male has spurs which produce a cocktail of venom, composed largely of defensin-like proteins (DLPs), three of which are unique to the Platypus. The defensin proteins are produced by the immune system of the platypus. Although powerful enough to kill smaller animals such as dogs, the venom is not lethal to humans, but is so excruciating that the victim may be incapacitated. Oedema rapidly develops around the wound and gradually spreads throughout the affected limb. Information obtained from case histories and anecdotal evidence indicates that the pain develops into a long-lasting hyperalgesia that persists for days or even months.Venom is produced in the crural glands of the male, which are kidney-shaped alveolar glands connected by a thin-walled duct to a calcaneus spur on each hind limb. The female Platypus, in common with echidnas, has rudimentary spur buds which do not develop (dropping off before the end of their first year) and lack functional crural glands. The venom appears to have a different function from those produced by non-mammalian species: its effects are not life-threatening but nevertheless powerful enough to seriously impair the victim. Since only males produce venom and production rises during the breeding season, it is theorised that it is used as an offensive weapon to assert dominance during this period.[

I am assuming that you mean a PLATYPUS??
