Most often, the treatment for a nerve injury is nerve repair surgery because if it is left untreated, the growing nerve fibers can form a painful nerve scar.
“Nerve repair is simply freshening up the end of the nerve and suturing the ends of the nerve back together to allow for repair,” says Dr. Riggenbach.
During surgery, the damaged part of the axon around both ends is removed. Then, the axons are sewn together. Overtime, the nerves will grow together and restore nerve function. The recovery time depends on the level of the injury.
“Depending on the level or injury you can expect potentially rapid recovery over the course of three to four months, potentially to a year, to 16 to 18 months,” Dr. Riggenbach says. “It depends on what level of injury you sustained and how far away that injury is from the structure that you’re looking to have function in.”
