I am a 25 year-old male, who up until this last August was fairly healthy. I am about 30 lbs over weight but that's it. I have been having abdominal pains (more like pressure, not severe)sometimes in specific locations: just left of the belly button, upper left and/or right colon area just below the ribs, just below the sternum, and general discomfort throughout the abdomen at times. Over the last 2 years I have had short bouts of constipation and diarhea, none lasting longer than 3 days and not that often. I also have anal itching after a bowel movement, this started around the same time as the abdominal discomfort in August. I feel pressure around the pubic area sometimes but am still able to urinate fine.Eating seems to bring it on, so does thinking of it. I have had CT scans, ultra-sound, barrium enema, prostate exam, urine tests, x-rays, and blood tests. Everything came back normal except I had borderline levels of bilirubin in my liver (dr not concerned). I have no visible blood in my stool, no blood after a movement in the anal area, I have done a hemoccult test and sent it in and am waiting the results. Some days are better than others, yesterday was my best day. My dr referred me to an accupuncturist and I had my first treatment and I was doing really well all day until just after dinner. Then this morning I was awakened by severe cramps and diahrea. I want to believe that this is IBS, I have a high stress job and had a cancer scare in august, the pains appeared 3 days before my surgery consult (tumor was benign). I'm at my wits end. Please help.
