Hi,
I'm a 22 student... Not that long ago a few months back I noticed my bowels were acting funny, I was having much more gas than before, could hear air moving around in my tummy etc... (no hickups or burping, not more than usual - since I think I read this might be a symptom too)...
I gave it absolutely no thought, since I could hold it, and not (xcuse the word) fart in public it gave me no real problems... Occasionally, if I was in a real quiet enviroment others could hear my bowels work (air move around), but as I said I could hold in the need to pass gas...
About a week or so ago I got some chest pains (not really chest pains, as by my feeling they are located in between the skin and rib cage). I first, as I remember it, got it sitting down in class, my posture whilst sitting isn't that good... Got it couple of other times, also sitting down in front of the computer (I'm a CS student, so I sit in front of the computer quite a lot...), even lying (not completely lying-more like slouching on the soffa), That kinda worried me since I had no chest pain ever before, and being only 22, I went to the dr. Told her about the chest (didn't mention the bowels, didn't seem important and related to me). So, she instructed me to have some blood work done, an ecg (or is it ekg), listened to my chest, all of the test came up with no problems found... Well, something was a bit raized (almost borderline upper normal value - in my language it's called bilirubin in the blood) and that led her to suspect that my liver was enlarged, so I did an ultrasound of an upper abdomen and a test for an adeno virus... Ultrasound came up with no morphological changes, all normal, and the adeno (or is it adino) test was negative, I had no virus... After those two tests I had experienced a couple of days without pain (not a pain as much as something like a blunt sometimes pressing sensation, sometimes felt, certainly not all the time). Kinda like I strained something. I haven't been to see my dr. yet with the new results but I don't know weather or not to mention my bowel trouble??? Do you think it's relevant? It was almost bothering for two months or more, before I got those chest pains...
Do you suggest any treatment?

Some more relevant things, I'm not so sure weather it was when I started doing intensive training or after I stopped, but certainly no before that I got bowel problems... That was last year, late november, I was working out for 2 hours a day, since the I stopped, almost completly, first I had exams, after that I got the bowels, and now chest... For the last mont no workout at all...
I'm rather thin, have about 155lbs, 6 feet tall... I also noticed I got a bit bigger in my pants, though that's probably just cause I had tossed on meaner abs back when I was still working out... I did a lot of (even traditional) ab push ups, english ain't my first language and I just can't remember the proper name of the workout now. It's on the tip of my tounge, though. It's a workout when u raise yours upper torso from the lying position....
I also recently, some 3 weeks before I got chest aches changed beds, it's much firmer than the one I used to sleep on before... I don't just sleep on it, I some time kinda lie down and read, again I know, in not a such posture perfect position...

Thank you... in advance
