I am having a slight itching sensation in anus, it's not persistent or constant sometimes i had burning sensation when i go to stool and feel itchy ?

This is not an: uncommon malady.A vicious cycle can occur when that delicate tissue becomes irritated and inflamed causing more vigorous attempts at hygiene with every BM.This,in turn,causes more inflammation/irritation,etc,etc...Gently clean with an over the counter steroid after BM's,and otherwise try to leave the area alone.No washing with soap,etc.
