According to Souza, numbness due to overuse or direct trauma with weakness and hypesthesia on the skin may indicate compression of which structure?

Compression of a peripheral nerve occurs when the nerve itself is pressed along its course, often after overuse or a direct injury. This leads to weakness in the muscles the nerve supplies and numbness or reduced sensation (hypesthesia) in the skin areas served by that same nerve. The sensory and motor deficits stay within the distribution of a single nerve, rather than crossing into multiple nerve territories or following a spinal segment. If the problem were a nerve root, the sensory loss would follow a dermatomal pattern and the weakness would align with a specific myotome, usually with back or neck pain and often changes in reflexes. A brachial plexus issue tends to affect several nerves and produce more widespread, multi-nerve symptoms. Spinal cord compression would produce more extensive signs, such as bilateral problems and upper motor neuron findings below the lesion. The presentation described fits a peripheral nerve compression most closely.
