Many individuals with one or more of these symptoms, particularly pain in isolation, have musculoskeletal problems. Some of these individuals may have sensory symptoms as well. Although this suggests nerve involvement, it is not uncommon to be unable to find objective evidence of nerve pathology particularly if the sensory symptoms are intermittent and vague in their anatomic distribution. By the same token, many of these patients have the perception of weakness that may result from limitations imposed by pain. Not uncommonly, however, patients with complaints of limb pain, sensory symptoms, and altered function will have focal nerve injuries affecting the nerve roots, lumbosacral plexus, or individual peripheral nerves, the subject matter of this chapter.
