I was wondering if anyone had the same problem almost everything i eat i get a stomach ache and when i eat gluteen free stuff im kinda ok.I also noticed though ill get a stomach ache from drinking water? I dont always have water but im trying to get into the habiit of drinking just water its just a turn off from water when i do get the stomach aches.I have been for tests like ultrasounds etc and they never find anything.Is it normal to get stomach aches from drinking water
