Randomly in the middle of the day, my stomach started to hurt, like a dull ache thing and when I ate it went away, I thought it was hunger, but after a little while it came back and it's freaking me out. I took some pepto and it's still there. It's fine when I'm sitting down, but when I get up, it hurts, and then goes away, and then when I sit down it hurts, then goes away. It's really scaing me, I'm really afraid of stomachaches because I had one when I was little and it led to....well you know....and from then on I am terrified of them Any idea what it is?
