Welcome! We're sorry for the delay in response to your question as we appreciate your posting on our forum. By now, you've likely seen your doctor and can update us on the situation. ‘Cam’ type femoroacetabular impingement describes a ‘bump’ on the surface of the femoral head (ball) which jams on the rim of the (acetabulum) socket. It normally affects young men. In cam impingement the femoral head is not round and cannot rotate smoothly inside the acetabulum. For some, athletic activity led to it developing. A bump forms on the edge of the femoral head that grinds the cartilage inside the acetabulum. Your doctor may recommend hip arthroscopy to treat this. But before going invasive routes is likely to try corticosteroid injections at the location to reduce inflammation. Physical therapy, Nsaids and rest can also help. https://my.clevelandclinic.org/health/diseases/21158-femoroacetabular-impingement-fai Please let us know any updates!
