hey i'm a 17 year old girl and when i was 16 and 15 i used to take large ammounts of pills. i would take tylenol and advil extra strength so 500mg several times a weeek because of depression and now a year later (i dont do it anymore) i have really bad pains. i have gone to a doctor to check for stomach olcers but they dont know what it is. the pains arent there ALL the time but when they do come they hurt and happen over and over again. Please give me some feed back on my possibilities?
