Some accidents can result in nerve damage, including compression injuries and severed nerves. When a nerve is damaged, nerve impulses are interrupted. In more serious cases, the nerve body is also damaged. A severed nerve can lead to paralysis of the affected limb or a loss of sensation. With any type of accident there is always the threat of nerve damage. Symptoms of nerve damage include numbness, loss of bladder control, limited range of motion for arms and legs, and chronic pain. Your physician can diagnose nerve damage through a nerve conduction test which measures the signals coming from your brain.
