I have been  having a bloating feeling in my upper and lower chest area, kind of feels like im really fat kind of... shortness of breath and i sometimes have to breath deeply. Also i have been having pain in my upper arms, where the byseps are and pain in the side of my chest, just beside arm pit.
Thanks for your question on Chat Doctor. I can understand your concern. Left sided chest pain, arm pain should always be evaluated for heart diseases. So get done ECG, 2d echo and stress test (trade mill test). If all these are normal then no need to worry about heart diseases. Gastritis can cause bloating and left sided chest pain. Bloating can in turn cause difficulty in breathing. So take combination of pantoprazole (antacid) and levosulperide (prokinetic) twice daily before food for 5 days. Avoid stress and tension, be relaxed and calm.Don't worry, you will be alright but first rule out heart diseases. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
