See doctor: there are many things this could be. Herpes can cause bllisters and be cyclical, and boils can happen. You need someone to look at it WHILE it is there, so you know for sure what it is.

Hidradenitis: This could be a manifestation of hidradenitis, which is a recurring infection of the sweat glands in the groin and armpits. However, without seeing it, it may be something else like herpes or something more rare. It would be prudent to see a primary care doctor or gynecologist about this.
