I'm by no means an expert, but I have done a little bit of online research on stomach problems a little while back when I was having problems. A lot of people described a burning sensation when they had ulcers....Any chance that what it could be? If it doesnt go away, i'd go to the docs and get it checked out. Good luck and hope you get to feeling better.

I know you posted this awhile back. But I also had the same symptoms ..I let it go forever just taking motrin. It ended up being much serious. I ended up having my right kidney removed. It had a 4 inch stone in it..And was fully infected. By know means do I want to scare you. But if you have not had this taken care of ..And it still hurts...Have your dr get you a cat scan and ultrasound of your kidney to rule it out. Good luck
