I am 18 and I have been having very severe stomach pain throughout the day and night for about 3-4 months now . It hurts mainly on both sides of my lower ribs and in the middle of my stomach is very very sensitive. I was diagnosed once with acid reflux but I know this pain is completely different. I can't sleep because I'm in so much pain and it will subside for about an hour or two after I drink A LOT of water but it always comes right back; even when I eat, the pain only subsides for a little while but never fully disappears. This stated in the summer time of 2013 but was just on and off and only during the night , then about 2 months ago it just became a permanent thing, lasting all day and night. i don't know what to do ... Going to see my doctor soon.
