### input:
Hi,Im a 45 old male, quite healthy and athletic, playing competitive tennis three times a week and running, doing sit-ups and push-ups almost every night for 30 times each, non-smoking.About 7 month ago, I felt sudden stabbing pain in my left chest area, followed by a feeling of warmness rediating and releasing from where the stabbing pain originates, followed by nausea and fatigue. This happened three times in a period of 40 minutes. I had ECG and Holter monitor on the next day and everything came back fine. Since then, there has no more stabbing pain, but it develops into a pattern of sudden onset of severe chest, back and sholder pain with slight nausea, very deep and dull, worse off when I stretch or tilt back or trun my head left. Had my blood test, stress test, ECGs a few month ago and Dr dont think I have heart problem. One thing I want to mention is that I did have tremendous pressure in life and some anxiety issues when this first happened, could this pressure and anxiety cause my problem?I have been trying meditation, relaxing techniques since and i do think I am really relaxed now, sleep well and enjoy life more. But this sudden onset of deep chest and back pain (at the bottom of my left shoulder) happens almost once a day, lasting about 30 minutes each time with slight nuasea.I now know this deep chest pain will not kill me but still get worried and annoyed when it comes on.Can you please advise as to what it is and how I can get rid of this completely.Thanks heaps,Dave
