7 Things Your Nerves Need to Heal: What the Research Shows

Many people are told that once nerve damage is done, all they can do is manage symptoms. But peripheral nerves have their own repair machinery, and fibers can regrow at roughly a millimeter a day, about an inch a month, when the conditions around them allow it. Drawing on more than 20 years and over 3,000 procedures as a peripheral nerve surgeon, Dr. Fitz explains that surgery could take pressure off a nerve, but the nerve did the healing, and how well it healed depended on the body it lived in. He walks through seven factors that shape that environment, from blood sugar swings and exercise to specific nutrient forms and sleep, with an honest look at what the research shows and where it is still uncertain.
