Hi, I am a 18 year female, and I have been having stomach pain for about 4 months now, and I have already gone to the doctor around the second month, they put me on a probiotic and it helped for a while. I am still taking the probiotic but the pain has come back. Also I have been peeing a lot today, at first i thought it was from the lots of water i have been drinking, but i stopped drinking it for the past two hours and still am peeing frequently..
