Guest guest Posted August 11, 2000 Report Share Posted August 11, 2000 In the area of original nerve damage (e.g., hand or foot), the hyperthermia points to damage and paralysis of vasoconstrictive function of sympathetic system (the central hyperthermic area). The central hyperthermia usually points to the apex of damaged tissue resulting in heat leakage, as well as accumulation of substance P and nitric oxide. This is an important therapeutic clue to avoid further trauma. Traumatic procedures such as surgical exploration, nerve blocks, Clonidine Patch, Capsaicin, or EMG needle insertion should not be applied to the damaged hyperthermic area in the extremity which may lead to further damage and aggravation of the condition. In acute stage, the damaged area is hyperthermic. After a few weeks, the hyperthermic area shrinks. In some cases the hyperthermia persists due to permanent damage to sympathetic nerve fibers. This bodes a poor prognosis. Well, I had an EMG, cortisone injections in every metatarsal head of the original injury and of course nerve blocks.
