Summary of past 12 months. Started feeling heartbeat through chest only when lying down. My Dr. diagnosed pectoral tear and inflammation was causing the feeling. No imaging done. She prescribes lots of rest and no physical activity. I followed her directions for 3 months and problem did not go away. Although she was sure not a heart problem, I was concerned. She did EKG and Echo - both normal. Told me to keep not working out. I went to a Sports Ortho who did Xray, CT scan, and MRI - No tears, breaks, tumors, etc.. Nothing bad on any scans but the discomfort persists. On a day when I do no activity its not terrible, I just cannot sleep on my left side and I feel minor discomfort. If I even run 1 mile, the next day - not the same day, I am in discomfort all day sitting, standing, etc... At this point my Dr. says heart is fine, all imaging shows no structural distress. The only time I experienced actual pain was jumping rope and it was more underarm area than heart area and the discomfort felt daily is down the side of the chest wall, heart area. Pulling off a sock the other day brought a very quick stabbing feeling also under the arm area. A few month ago while stretching I felt a "Charlie horse" or muscle spasm in the pectoral area.
At this point I do not know how to process in terms of even getting it diagnosed. Its been just under a year since this began and today it is no better than a year ago. I have gained 20 lbs in the past year not being about to do anything more than walk without being in discomfort the next day. Its very frustrating and I don't even know who to go see at this point to maybe get a diagnosis.
