Yes, nerves can regrow, although the process is slow and can vary depending on the type of nerve and the extent of the damage. Peripheral nerves, which are the nerves outside of the brain and spinal cord, have the ability to regenerate to some extent. This regrowth can be supported by holistic treatments such as shockwave therapy, proper nutrition, physical therapy, and other natural approaches that promote healing and improve blood flow to the affected areas. While complete recovery may not always be possible, especially in severe cases, these treatments can help stimulate nerve regeneration, reduce symptoms, and improve overall nerve function.
