How long will it take a bruised nerve in my head, near the back of my right ear to heal? been suffering for almost two weeks. thanks

Depends: Damage to the nerve can recover within a few weeks if the problem requires simple localized re-myelination of the nerve sheath. If the nerve axon was injured it takes longer to heal. (Wallerian degeneration followed by re-sprouting of the nerve axon and successful navigation down the hollow nerve sheath back to its original location.) This depends on the distance the nerve has to "travel" (months)
