I have been having really bad stomach pains for a few months now. One time when I woke up from sleeping and was about to go to the bathroom, my stomach started to hurt so bad that I couldn't even move and curled up in a ball. When I finally got up ( my stomach still hurting really bad) I started feeling dizzying I felt like I was going to throw up. I also started seeing black star all over like I was about to pass out and there was a ringing noise in my ear. When I finally went to the bathroom (number 2) all my pain was gone. To remind you, this has happened to be before but it doesn't happen constantly ( maybe every few weeks)
