I am a 20 year old male. I am 6'0" and weigh 154. Since around Christmas of last year I have been constantly experiencing pretty strong pains in the upper right quadrant of my abdomen, which get extremely severe at times. A few of the attacks have been so severe I have collapsed and have been transported by EC unit to the ER, requiring opiates to ease them. Along with the attacks come severe nausea, vomiting and shortness of breath. During some attacks, the pain radiates into my right shoulder. The worst attacks seem to occur after eating a particularly greasy meal, and where I'm from, if it's edible, it's usually full of some kind of grease. Gravy seems to be the worse culprit of all. I have modified my diet to include less grease and fat, however, the pain persists. I have saw a GI specialist, had more CT's with and without contrast than I can count, 3 ultrasounds, x-rays, blood work, etc. Each time, I am disappointed to discover nobody has a clear diagnosis. Between myself and my co-workers (I am an EMT), we suspect it's my gallbladder. However, my doctor maintains that it would have shown up by now and he has put me on medicines used for ulcers, abdominal and intestinal distention, and many other medical conditions with absolutely no success. I am starting to get really discouraged and somewhat depressed that nobody can find what's wrong. Am I going crazy or is there something I could be overlooking? Any ideas of what I could do to be rid of this problem for good? Medical co-pays and sick days are difficult to come by when trying to start a family, pay off a house and car, and keep food on the table, so continual visits to the doctor aren't really an option which really makes things difficult. Side note: I recently learned my mother had the same problem develop when she was pregnant with me. She suffered for close to two years before doctors decided to to remove her gallbladder, and has not had a symptom since.
