Approximately two days ago I began to experience severe leg pain. This includes the calf and knee. I had a TKR 7 years ago, have had no problems. I have Type 2 Diabetes and High Blood Pressure. My glucose has been high, averaging 130. I take Metformin, Vytorin, Lisinipril, Oxybutinin, Trileptal and Cymbalta. Am debating if I may have a blood clot or worse and if I need to see a doctor. I did take 660 mg of Naproxen approximately 6 hours ago. Seemed to help, but pain is now in back of thigh. Suggestions
