I have pain in my chest just below my rib cage.When I try to do any physical activity like walking ,the pain becomes sharper in my right upper chest.When I take a deep breath I fill congestion on the right side of my chest.If I am walking for about 20 minutes and get a good belch,the pain eases off and I can breathe better. I had had 2 stents inseted in my heart,but the conditions remain the same.The cardiologist assures me that my is ok.Had test done for chest muscles,Gastro Intestinal test with no luck.
