I recently had to go to the ER because of an oral abscess on the lower right side of my lower jaw bone. I was put on penacyllin 500 mg 4x daily after they refused to drain it. The abscess was over 2" x 2" and wrapped around beneath the bone down my neck and up the bone to my right ear. Now my tongue has very red areas on it, it bleeds and is so pain full that drinking water causes excrutiating pain. I also just noticed that I have an ulcer type sore on the upper jaw on the left side. I have no idea what this is, just want the pain to end! I have only eaten very small amounts f food since Thursday the 12th, do I even need to say that I am starving! Please if anyone knows what this is or nows something that might help, let me know. Very desperate floor help.
