3 weeks ago I started going to a great chiropractor, shortly after, I started having trapped gas pains in upper chest but was having difficulty burping. It s gotten so painful & so often , I went to see a doctor. I notice I m not pooing per my intake of food nor passing gas. I took magnesium citrate , not much happened. The upper gas builds, pressure is unbearable but even with Zantac, nexium, gas x, no gas, alka sheltzer tablets I can t burp enough to get relief. My upper ephofageal sphincter will not release & I ache from the front of my chest thru to my back. I ve had H-pylori severely, many times but this feels different. Help
