hello Dr. Im having some oral mouth pain. It started Sunday. I thought it was from a tooth so I went to see my dentist Monday morning who replaced a filling I had with a medicated filling. but the same pain remains. let me explain the pain that I m feeling. Its my lower right jaw, teeth, gums, and right ear. the pain has only gotten worse since it began. after realizing it wasn t a dental issue I thought maybe it was a sinus congestion issue. so starting Tuesday I started taking sudafed congestion and Ibuprofen but still no change. the pain is really bad enough that I can t sleep, and the only thing that seems to help is running cold water inside my mouth over the area and then the pain will subside but only for a couple minutes until I have to do it again. I don t have alot of money so going to the hospital is not an option unless i know I ll get what i need to fix this. instead of blowing money on things like the dentist which turned out to be not the problem and a waste. so please can you give me your best guess on whats wrong with me and how I can best treat it.
