Hello 43 yr male with on and off stomach problems for two yrs. it started suddenly with nausea and semi soft stool. Now two yrs later I have episodes of nausea lower/middle abdominal discomfort and acid reflux. I also have loud intestinal noises usually preceding. Sometimes go 3-4 days between bowel movements and other times it feels as though I may have diarrhea but can't go when I try. Always have had nervous stomach but since this started its gotten worse. It seems as though just only a beer or two would make me nauseous and have stomach cramping the following day. I do take dimenhydrinate/mine for the nausea nightly and wonder if this could cause gastritis or ulcer. I am slight emetophobic so I'm sure that doesn't help. Am in a episode now and had movement tonight that I thought was loose stool but was white foam. Not much smell. I also notice that at times there is brownish stringy stuff mix in with bowel movement. Hopefully not a parasite. I can go a week feeling good and then bam out of nowhere I get a burning nausea and discomfort. Sometimes it hurts to push on lower abdomen usually left side. Any ideas? IBS? Ulcer? IBD? Anxiety which I have had for years??? Thank you
