I went to GP today for the second time in a week. Having abdominal pain (lower, in front, waves of it extremely painful), tenderness, and bloating. I was constipated, but after taking Milk of Magnesia the other day, it at least is moving along again. GP seems to think it's bowel spasms or IBS and prescribed Buscopan tablets. I've taken a couple doses today, and there's some mild relief, but still getting pain when standing up and walking around. Is this typical of IBS or colon spasms?
