For the last one month now I have been experiencing some sort of ‘rash’ between my butts ( on my anus) It is extremely itchy at times and when it gets really bad I apply betamethasone cream to ease the itching but that doesn’t even seem to help. when it starts to itch it literally feels like pinpoints of itchiness in the same places on my anus.For a while I have been scared that I might have genital herpes because in the past I have gotten really bad cold sores in the corners of my mouth.I want to know the reasons for itchy anal?
