I have been suffering from a lot of deep belly aches from my IBS this week, I suspect that I ate too much trifle on new years but the last day or so I've been getting a lot of pressure feeling along the bottom of my ribs. Today it seems to have gotten worse and I have a wierd sickly feeling in my stomach, I cant get a decent breathe without gasping and shaking and I keep coughing violently, more like a retch. I've taken some pepto bismol but was wondering if this is something other people get and if they have any tips for it? Is it as simple as indigestion and gas making me feel like this?
