Characterized as a burning, pins and needles sensation, with occasional thinning of the skin and loss of hair. There are two types of CRPS, Type I and Type II: Type I, formally referred to as “reflex sympathetic dystrophy,” and Type II, formally referred to as “causalgia,” when a specific nerve is involved. CRPS can be treated with medications such as Neurontin and Lyrica Topamax or locally if “early by stellate ganglion blocks for the upper extremity or lumbar sympathetic nerve blocks in the lower extremities.” Alternatively, this can be treated using spinal cord stimulation.
Description coming soon
Injury to multiple nerves due to either metabolic or genetic abnormality. The classic example is diabetic peripheral neuropathy, which is usually diagnosed by EMG/nerve conduction study. Although this can be treated with neuropathic medications such as Lyrica, Neurontin and Topamax, tricyclic antidepressants, or SNRIs, it can be treated with sympathetic nerve blocks such as lumbar sympathetic nerve blocks for the lower extremity and stellate ganglion blocks for the upper extremity. Alternatively, this can be treated with a spinal cord stimulator.
This disorder occurs after an amputation where there is confusion to the nervous system and no inhibition of pain fiber stimulation.
