Hello!! I'm suffering from irritable bowel syndrome and my bowel hurts when I drink beer or I eat some food like chips. Should I take a painkiller when I feel this insufferable pain or should I take antispasmodic like buscopan? Also when I'm out every n

Avoid the foods. I think the best answer would be to avoid the beer and chips and opt for choices that don't cause insufferable pain. If you get the pain then either medication can help. Pain meds can cause constipation so if you have IBS that is predominantly constipation I would avoid opioid pain medications.
