Butt continually hurts and burns plus itiches every night, this has been going on about 2 months what can cause this?

Pain and itch: Quite often, pain and itch indicates hemorrhoids and/or an anal fissure. There is also the possibilities of small intestinal parasites (e.g. Pinworms). The best thing to do would be to visit your doctor and have him to a thorough examination as well as tests for o&p (ova and parasites). Once the diagnosis is made, treatment can be started.
