Blister on leftside of anal crack every 2-3 week?
3 doctors weighed in across 2 answers
Is it one blister or: If it is only one blister it could be from pressure if you lean on that side a lot. If there are several small blisters in that area it may be herpes. If possible see your dermatologist when you have the blister to see if a diagnosis can be made.

Difficult to say: But it is most likely infection (perianal abscess), std (herpes), or hemorrhoid. But it could be something serious such as anal cancer, so it is best to show it to a doctor for definitive diagnosis.
