ITCHY

So lately it was just around my anus that would be super itchy especially if i needed to have a bowel movement but within the past few days everything “down there” is itchy. I can barely stop scratching. There’s no discharge or bumps just itchiness and of course a cut or two from itching too hard. Does anyone have any idea what it might be? I thought it was just hemorrhoids but now that itching has moved I’m concerned it’s something else. It’s also so bad I’ve been unable to wear thongs because they add to the itching sensation.
