iam 25/m and have symptoms of IBS for over 2 years now.iam afraid to eat anything because of the bad stomach pains i get afterwards.i have talked to the doctor about my stomach problems,but havent been able to figure out the stomach issue.i want to get a colonoscopy,but iam unsure if i should just ask for it directly,or keep on about my IBS symptoms?it gets frustrating not knowing whats wrong.thanks
