When numbness with weakness and reduced skin sensation occurs after overuse or direct trauma, think compression of a peripheral nerve. Peripheral nerves carry both motor and sensory fibers to the same region, so squeezing or entrapment can produce weakness in the muscles they innervate and hypesthesia in the skin over the nerve’s distribution.

If a dorsal root were compressed (radiculopathy), sensory loss would follow a dermatomal pattern and motor effects would be less consistent unless multiple roots are involved; spinal cord compression typically yields bilateral signs below the level and often upper motor neuron signs rather than a focal nerve distribution. Central nervous system involvement would present differently, with more widespread or higher-level deficits.
