Neuropathic pain is caused by damage or injury to the nerves that transfer information between the brain and spinal cord from the skin, muscles and other parts of the body.
The pain is usually described as a burning sensation and affected areas are often sensitive to the touch. Symptoms of neuropathic pain may also include excruciating pain, pins and needles, difficulty correctly sensing temperatures and numbness.
Common causes of neuropathic pain include nerve pressure or nerve damage after surgery or trauma, viral infections, cancer, vascular malformations, alcoholism, neurological conditions such as multiple sclerosis and metabolic conditions such as diabetes. It may also be a side effect of certain medications or chemotherapy.
