i've been having this stitch pain in my stomach on my right side by my hip, and today it was the worst it hurt to walk very badly, this has been going on for months. i also have a stitch pain in my left lower rib for a lng time and my overall lower gut has been hurting like little stitch/knots everywhere. i am very worried today since the pain/stitch on my right is hurting badly. my bowel movements are usually hard and are hard to get out. i was on antibiotics for 2 weeks could that have made my stomach hurt more now, what could be wrong with me and has anyone experienced this? could it be anxiety or acid reflux? is this dangerous
