I am a 44 year old woman, had a t-bone accident about 12 years ago and suffered injury to sternum, alon g with severe whiplash. A year or so later I have suffered with mid sternum pain, throat squeezing, heart flutters and near fainting. I have been on paxil, metoprolol and buspar, and Robaxin. I am sometimes symptom free, and then the symptoms return. I have been seen by cardiologists, endocrinologists, allergists, gastrointerologists,. Help, I have run out of answers.
