Upper abdomen pain with severe bloating and gas

I have had these exact problems and although I don't have the energy right now to type much please see my posts as they will be very helpful to you. 

I am nearly 2 years post take down and still having severe gas, the best thing to do is take a hot bath with hot tea and let it rip until you feel relief. Gas-X doesn't stop gas however it helps break down small gas bubbles into large ones that are easier to pass. Seriously though, read my posts you will find the feedback from others very helpful.

A member here also suggested I may have SIBO which can be create with antibiotics and diet and SIBO can cause to severe gas.

Let me know if you find anything that helps, I have tried cutting out dairy, gluten free, vegan, no added sugar, you name it. 

Am wondering if you could have a peptic ulcer (stomach ulcer) or a duodenal ulcer (ulcer where stomach leads to beginning of small intestine). In any case, your symptoms have continued for a long while and should be checked by your doctor.

You may be experiencing a partial blockage, you would feel bad and would cause "constipation" and the other symptoms. You may still be partially blocked. I definitely think you should consult with your GI.

When I have had partial blockages I usually get on a liquid diet to help things out. Make sure to keep moving to help things along. I also end up taking antibiotics because pouchitis usually follows. Pouchitis also seems possible, I feel similar but not actually constipated.

Good luck
