How long does it take for damaged nerves to repair themselves? by Connie b. Dellobuono
Answer by Connie b. Dellobuono:
Once the insulating cover of the nerve is repaired, the nerve generally begins to heal three or four weeks after the injury. Nerves usually grow one inch every month, depending on the patient's age and other factors. With an injury to a nerve in the arm above the fingertips, it may take up to a year before feeling returns to the fingertips. The feeling of pins and needles in the fingertips is common during the recovery process. While this can be uncomfortable, it usually passes and is a sign of recovery.
I hurt the tip of my little finger (by bumping it to a cemented wall) yesterday with a small redness by the nail bed. It healed in 12hrs as I massaged it right away (w saliva).
