I found this article on IBS, which I have, IBS-C....and any changes in diet or medication worsen it.
I have a lot of similar symptoms, however am not a doctor, so can not say this is what you are experiencing.
If you feel like this article has similar symptoms to yours, please bring this to your doctor and discuss it:

Hello~The fact that it hurts to the touch could mean it is "Costochondritis" (inflammation of the ribs) this can hurt very badly and even mimic the pain of a heart attack. I suggest possibly seeing a chiropractor, he/she will take some x-rays and your history, after reviewing them, he/she will then discuss the results and if chiropractic will be able to help you. Also, possibly therapeutic massage might help some.
Have you received an ultrasound exam? It can diagnose an enlarged spleen, a "rub" caused by dryness in the area, or perhaps a bulge in upper loop of your large intestine. Pain can be "referred" in most unusual ways, so it could be caused by something not real near the pain, such as your stomach, esophagus, or even an arthritic spine. Best of luck, keep us posted!
It can be really confusing! I will say that the upper left quadrant pain IS a symptom of a gastric ulcer. There is a chance they'll want to do further tests and perhaps even an endoscopy. You can have ulcers from other things such as biliary reflux (that is how I had mine). Bile backed up and burned a little ulcer into the top part of my duodenal.
Your spleen, though, is also in that area. It could possibly be enlarged.
Then there is your pancreas near that area.
So, I'd definitely move straight to determining if this is gastro related at that months end if the pain persists and then also make sure there isn't anything else going on. I would imagine that your doctor has checked for these things. But that it hurts when you move and is sore to the touch, that really would be a bit odd for an ulcer and perhaps really IS something like your spleen.
