Health condition: annoying

Another day in paradise. I'm in stomach pains. This morning I had to turn around on my way to the train station and return home because I couldn't stand the pain. I rested half an hour or so, and then I went out again. It is still aching, and I know it is the sort of pain that comes from stress, so extremly annoying. I am not a hypochondriac, but inner nose-bleed and constant stomach pain gives me a pretty bad feeling.
