The peripheral nervous system consists of the nerves outside the brain and the spinal cord. Whether caused by injury, surgery, or conditions like diabetic neuropathy, damage to the peripheral nerves can lead to chronic pain and is difficult to diagnose.
Three main types of nerves can be involved in peripheral neuropathy. Sensory, motor, autonomic, or a combination of any of the three. Neuropathy is not a single disease. It is a complication found in many underlying medical conditions. Impaired function and other symptoms depend on which of the three types of nerves are damaged.
Diabetic patients usually experience numbness, pain or burning sensations in the upper and lower extremities as a result of the effect of diabetes on the nerve and the compression of nerves within tight the tunnels. If neuropathy symptoms continue along the anatomical nerve compression sites despite medical care, referral to peripheral nerve surgeon is required. If peripheral nerve surgery is performed in time, it can prevent permanent nerve damage (permanent numbness).
As for other common neuropathies, it is very imperative that surgical treatment for being done promptly. If it is prolonged, any intervention to stop the progression can lead to irreversible nerve damage.
