I'm sorry for the novel you're about to witness, but I've been battling this thing for a little while (and writing down the symptoms as they change), and my nerves are shot.
I'm 28, Male, and around 245(trying to cut down). I do have problems with acid reflux, and have for a long time. I'm on a 20mg dosage of Omeprazole per day, and even that doesn't help all the time. Around 4 years ago, I went to the ER for bad pain in my right side. They ran a few tests, and the doctor seemed to think I had a bout of colitis. I ended up consulting a Gastro about the problems, and ended up getting a colonoscopy, as well as endoscopy, neither of which showed any problems in the slightest. Cut to around 2 years ago, and I have the pain return, but in the other side. Again, after an ER visit, nothing showed, and I went on to be alright, with occasional bouts with duller versions of the pain off and on, until now.
For roughly two and a half weeks, I would begin getting dull , but persistent stomachaches. 95% of the time, it happened after/during the lunch time hours in the day. I thought it was something I had been eating, so I began to cut things out of my diet (started with dairy, and greasey foods) to no avail. Also throughout the week, I had been using the bathroom fine, with normal, healthy stool, but I began noticing a yellow discoloration on the toilet paper afterwards.
Cut to this passed Saturday night, when I began to experience a dull ache in the right side of my abdomen, around the ribs. I was hoping to sleep it off, so I just tried to ease my anxiety, and go to sleep. Sunday morning, I decide to make two eggs to eat, and roughly an hour later, I had bad stomach cramps. I ended up with a bout of diarrhea , but it was an unusual consistency, sort of ribbon like and "fluffy" if that makes sense. It was also a yellow color, and extremely greasy (especially on tp). The pain also persisted in my right side, but not being anything truly bothersome. I set up an appointment with my doctor for the coming Friday to be safe. As the week continued however, the pain began to move; At first it went into my lower right back (almost feeling like a pulled muscle), then into my lower left side, and lower left rib area. Now, it feels like its in the area right underneath my shoulder blades on both sides, and I still have a bit of a nagging stomach ache. Also throughout the week, I've gone between constipation, normal stool, and then soft stool. Nothing even close to what happened Sunday, but still enough of a change to worry me.
On Friday, I had my appointment; my doctor seems to think it could be gallbladder related (which my Grandfather, and Mother both had serious problems with, leading to the organs removal), so he had blood taken , as well as sent me to get an ultrasound. I haven't heard anything back yet, unfortunately. I'm essentially writing this out to calm my fears, and to possibly get some further insight from the folks here.
My biggest concern is that the pain has been rather persistent, with or without food, and gets worse when too much pressure is applied to the area (like sitting against a chair/couch a certain way). I know that the symptoms are frighteningly similar to a couple varieties of Cancer, but I'm hoping that I'm missing something somewhere and it's not *as* bad as that.
