Under compression, the first nerve fibers to lose function are the ones that conduct sensation. As the sensory fibers “go to sleep,” the first signal perceived is the familiar “pins-and-needles” tingling sensation. Certain nerves are especially vulnerable to compression. People who sleep curled up with one hand tucked under their head put pressure on the median nerve as it passes through the wrist’s carpal tunnel.

Some diseases and conditions, such as the professor’s vitamin B12 deficiency, affect peripheral nerves directly. Others in this category include diabetes, rheumatoid arthritis, lupus, thiamine deficiency, and kidney failure. Sometimes neuropathies can result from too much vitamin B6,
