Lumbar Sympathetic Block

Lumbar sympathetic block is a procedure performed for treating Complex Regional Pain Syndrome (CRPS), or Reflex Sympathetic Dystrophy (RSD), of the lower extremities. Pain of CRPS is ofter burning, numbing and hypersensitive. It is accompanies often by swelling, redness and shiny appearance of the skin in the early stages. Over time, if treatments including physical therapy, sympathetic blocks and medications, the extremity can atrophy and lead to worsening problems.  Lumbar sympathetic blocks are performed to reduce sympathetic nerve hyperactivity, the hallmark of CRPS.
