I have IBS for the past 2 years now, but I always get sharp pains or constant pains around my abdominal. I went to see a doctor and they just keep saying the same thing which is its IBS. But it has increased in the past few days, I haven't been eating much sometimes at all and find myself very very thirsty. The pain won't go away its just there and I feel like throwing up all the time even though I've had diarrhea for the past few days. Any suggestions on what I should do or check on???
