About 6-8 months ago I went to the doctor because every time I went to the bathroom I would have a bloody stool. I had a colonoscopy done and they said everything was fine and nothing was wrong and the blood went away. About a 2 months ago I was rushed to the E.R. after experiencing the worse pain in my life. The pain was located at the lower right side of my stomach below my ribs. It started as weird pressure then gotten worse. The pain went away and then came back after I ate Burger King so that's when I went to the E.R. As I mentioned the pain was terrible. I through up while waiting to be seen by a doctor and it seemed to had made the pain decrease. I was then taken for a can scan where they told me I had a kidney stone and that it's already in my bladder and I would urinate it out within a day. Everything went fine that night. Pain then came back in the same area a day after but wasn't bad enough to go to the E.R. again. The pain didn't come back until recently where I get little random pressures and pains in the same area that come in go. I also get it on the left side now in the same location. I never peed out the stone. I looked up the human stomach and it looks like the pain is coming from my Left Colon and Right colon. What should I do?
