two days after my flu shot my arm started aching. six weeks later and my arm still hurts. should i call my doctor?
assuming you did not strain or injure your arm i feel that it is related soley to your flu shot i think it important to address this issue with your doctor. sometimes the needle used for the injection can cause a hematoma -- a pocket of blood at the injection site. this can cause an sterile abscess or even an abscess that is secondarily infected. get it checked out.
