Acid Reflux/GERD without any heartburn or burning feelings? Shortness of breath, pain below sternum,does not get worse when I lay down, frequent belching, low HcL

For the past four weeks i have been dealing with shortness of breath, chest tightness, pain around xiphoid process, pain in center of chest like a clenched fist. It seems to get worse when i eat, for about an hour, but sometimes it gets worse five hours after I eat. It does not get worse when i lay down. I feel no burning at all. The worst pain was after I'd eaten some ground beef, a few hours later. Bloating and tightness in middle of abdomen. Shortness of breath, to some extent, all the time. When i first get up in the morning my heart pounds and beats faster than it should just to walk across the house (and i am somewhat athletic, although I had to stop exercising when this began. When i tried to jog, the clench in my chest got worse and worse until I had to stop and lay down for two hours, and for much of that time i wondered if I was going to survive, with extreme difficulty breathing and chest pain.) I know i have low Hcl. I have been taking two Hcl tablets with protein meals but that is probably insufficient. I have been belching more and more. When I try to take a deep breath, there is pain under xiphoid process, in the soft area below ribcage. Leaning over sometimes helps me to get around this pain, when I inhale, but not always.

Any ideas about this? If it is GERD/acid reflux, how do i make it stop? Tweet
