I have these horrible lower stomach pains. Sometimes on the left, sometimes on the right. I can feel a little ball on the right all the time, when the pain is there, it seems larger & it hurts. On the left there is also a ball, but when it doesn't hurt, I can't feel the ball. I have had a CT scan at the ER, they said they saw nothing wrong. I think I have a double hernia, (I do heavy work). I am female, have had all the usual, (Ovarian ultrasound, HIDA scan, etc..) Nothing. This pain is horrible when it comes on. It never comes on when I am off work sitting around the house, only when I am up walking around & bending & doing stuff. Is it possible that a CT scan can miss a hernia? This is awful, it is ruining my life & the doctors are giving me pills for IBS, which I am pretty sure is not the problem. I mean, if you can feel a lump, something must be there, I am thinking.
