Just this afternoon, I have developed intense pain in my left jaw and ear. I cannot put my upper and lower teeth together. About 2 weeks ago, I had dental surgery on a root canal I had fixed years ago. The dentist said I had cellulitis and drained it for almost a week while I was on clyndimyacin for 7 days. I have a difficult time swallowing. In addition, I have Rheumatoid Arthritis, PAD, and Fibromyalgia, if that helps with diagnosis.
