The most common causes of sharp ear pain include otitis media, malignant otitis externa, and swimmer’s ear. These diseases are sometimes collectively referred to as ‘ear infections.’ Ear pain can also be caused by arthritis of the jaw, an object that is stuck in the ear or cuts the ear, sinus infection, ear injuries that come from pressure changes, and tooth infections. In many cases, an ear infection is treated with pain medications and antibiotics. These can help to relieve the pain and swelling.
