I'm not sure if I'm in the right place, but I hope someone can help.
Sometimes I feel (Mostly when I am sitting hunched forward at my desk, but sometimes standing too.) what I can only call a blockage under the right side of my heart. Perhaps it is best described like this: if you take a garden hose and bend that hose at a certain spot, then felt the water rushing through that bend/kink, that is what it feels like. It is sometimes followed by a cold drip-like feeling. I can stop this kinking feeling by arching my back and thrusting my chest out. The last time this happened, I waited, to see if the feeling would pass. It didn't; it only got more painful and then the muscles around my heart in the chest area got very sore and tender for a few days.
I've had numerous physicals and checkups and always got a clean bill of health. I'm not on any medications, am not overweight (although I am about 10 pounds over my goal weight) and I have exercised regularly (3-5 times per week) since I was 12 (I am now 35).
I have had other irregular aches and pains in this area before and there is no history of heart disease in my family. Any ideas what might be wrong?
