I recommend that you get in to see your Dr. There are several things that could be going on and I wish I could tell you what it is.
Does the pain happen after eating, is it higher, lower, on the right or left side of your stomach?
Higher. Both side. It is make me pain a lot.
Is it higher to the sides? Sorry to be asking so many questions but the more I know the better I can help. If it is a little more to the sides you may have a kidney infection. This will need to be treated by a Dr.
Have you been running a fever and or having burning during urination?
