Hello, for over a year now I have been having an aching pain in my abdomin on both sides right below belly button level. It is an achy feeling almost like when you have a bruise and someone pushes on it. It seem to ache both in the front and on my back. The pain comes and goes and can be gone for a few weeks and only last a few hours or a couple days. Lately when I get the aching it is getting more severe. I m pretty sure this is not associated with my menstral cycle. I m starting to wonder if this is something to worry about.
