No diarrhea, gas, or vomiting, just a fairly persistent and sometimes more severe stomach ache, with some times of relief, starting last Wednesday. Worse when standing out laying out straight. Water seems to help a bit, and while it doesn't sound great, food doesn't seem to make it worse.

How long should I wait it out before going to a doctor? I've had some amoxicillin some days for to something else, so a simple bacteria doesn't seem to be the problem.
