Sweating and Gas

Hi,

I have always had a sensitive digestive system but I caught a really bad stomach virus or infection and for the past 6 months the ibs seems to be worse. I had severe trouble digesting food and really bad reflux episodes. I think I damaged gut from the constant bowl movements and after taking some anti acids for a few months it has improved massively but I am still left with strange symptoms.

I am following the fodmap but I am still experiencing pressure in gut which I guess is gas but I cant release it and its worse when sitting down. My back feels like its going to push out and also my bladder feels under pressure. I am also sweating a lot more like the palms go sticky, clammy skin, my back feels hot and back of my legs/bottom. It seems to be when I have eaten something which I have trouble to digest. For instance I find some meats really hard like chicken, steak and then I get all this gas, sweating and almost like a tingling muscles feeling in some places.
I often feel I need to get rid of anything that's in my stomach to relieve the symptoms. I was quite stressed out by this all but have felt better past couple of months. I did have a lot of muscle tension all over which I think was probably stress too so I don't know if this has made it worse.

I haven't had much help for this apart from being told to go on Fodmap but even on this I still get odd symptoms. Tests all seem ok and I had allergy testing after I broke out in some hives but Dr said it could be stress on the gut.

Has anyone else experienced strange feelings like this and trouble digesting foods. Is there anything else I can do or try?
