There is nothing worse than intense
stomach pain, and diagnosing whatever is causing your issues could take a very long
time (an unfortunate reality). I was diagnosed with Crohns when I was six years old and it took 4 months. Stress of course makes every issue in life especially physical discomfort worse. Then there is the question of allergies and treatment. As you are waiting, and this is something small but it never fails me, and that's hot water.
