22 yo female, I have been experienced RLQ on and off for about two months. It usually starts to the right of my belly button and spread around to my back. I had my gallbladder removed 4 months ago, but no relief--also this is lower, I went to the ER a few times and they were always worried about appendicitis, but there was never a problem. I've had an endoscopy, colonoscopy, bloodwork, tissue samples, etc. and they have found nothing. It's pretty unbearable and I was just wondering if anyone had experienced they same thing. I'm at a loss what to do and everyone just keeps saying the same thing, but it doesn't make sense to me. How can there be this much pain? Something is clearly WRONG.
