for two weeks I was punched in the right jaw. I thought it was an ear infection. I visited my doctor and he saw fluid in the left ear but said the right ear was fine. He prescribed Aumentin and dexpak 6 day. Some days the pain goes away as the day goes on. however every morning the pain returns. today the pain has not gone away. what could be the reasons? I have not been punched nor had any related injury to the jaw nor are my teeth in pain.
