Nerves in the leg may become inflamed, compressed, or degenerated as a result of mechanical or chemical irritants. Nerves may also become damaged due to associated conditions such as diabetes or nutritional deficiencies. Depending on the cause of nerve damage, the specific leg symptoms may differ. Nerve pain is typically described as sharp, shooting, electric-like, or searing pain. It may also produce a sensation of hot or warm water running down the thigh and/or leg. In some individuals, a dull ache may occur.
