Feel like iv torn my anus, what can i to to stop pain during bowel movements?

You might have a tear -- which is common and nothing to freak out about -- or hemorrhoids. You can get relief from and advice about how to treat and prevent both from a proctologist. Presumably you're also working with a gastroenterologist. You're right to avoid laxatives if you can, although sometimes they're hard to avoid. Keeping hydrated and getting exercise can help a lot, as can old fashioned prune juice if it doesn't give you the opposite problem.
