Gallbladder or IBS?
About 3 and a half months ago I had an episode in the middle of the night. I threw up and had diarrhea all night. The next morning I went to the clinic, they took my temperature (no fever), and said it would probably clear up in a couple of days. After a few days I felt much better so I went back to my regular diet, but a few things upset my stomach and made me throw up more. Those include fried foods and something I found interesting was lactose (I now have to drink lactose-free milk). After I would eat these types of foods I would get an extremely full feeling, almost like bloating, but it wasn't gas. A few week after that I began getting a pain/pressure located directly below my rib cage in the middle of my abdomen, and after a few days it moved to the right of my abdomen. These pains could last anywhere from a few minutes to around 45 minutes was the longest. I also experienced a shoulder ache during this period (could be unrelated). I got an ultrasound (everything normal) and an upper endoscopy (no ulcers, etc.). I also received a HIDA scan, but they were unable to determine the percentage my gallbladder is working, so my doctor diagnosed me with IBS. I am fine with that and the pains went away for about 3 and a half weeks, but then slowly came back. After every meal I feel the same pressure in my upper right abdomen. I wasn't sure if I should still be concerned about my gallbladder (and if so, are there any more tests?) or if IBS can cause all of these symptoms.
Also, my grandmother and cousin had gallbladder disease which is why I was leaning towards my gallbladder to begin with.
