I am experiencing a warm tingling down left arm and chest. I have a burning sensation in my upper abdomen. My blood pressure is elevated to 124/80 pulse at 85. I don't have diabetes, high bp, or any other medical conditions. I'm currently on bactrim (?) for a sinus infection. I've been in the emergency room before for similar reasons, but I only leave with a bill, no real answers despite blood work, xrays, and an ekg. Any insight would be most welcome. This is a very scary feeling to have to endure.
