Cranial nerve damage could cause symptoms like Vertigo, hearing loss, facial twitches, or even paralysis.
Peripheral nerve damage could include symptoms like weakness or lack of coordination, paralysis, sharp or burning pain, sensitivity to touch, numbness or tingling, digestive problems, etc. Autonomic nerve damage symptoms could include things like dizziness, incontinence, erectile dysfunction, blurry vision, digestive issues, and more. You could have nerve damage in more than one location.
