Lately every time I eat I experience excruciating abdominal pain. The pain is so bad I no longer eat during or before work so I can focus on my job. Sometimes I get the feeling I need to pass gas but cant. I get really nauseous after eating and have thrown up a few times. My constipation is still bad even though I am following my gi and I’m unable to have a bm, I don’t know if the pain is because I’m constipated or something else. I tried an enema a few days ago and only the water came out. Because of this I’m losing a lot of weight.
