pea sized bump on perineum

Last year this pea sized bump showed up on my perineum, right below the bottom of the vaginal opening. I went to my gyn twice and both time she siad it was just a pimple and to use a sitz bath. Well I was too embarassed to go ask for the sitz bath, and eventually about a month later the thing just went away on its own.
The thing is, this week i got another one in the same spot. Its just a bump under the skin and when it was first there it was bleeding ever so slightly like a just popped pimple but there was no white head or anything. It only hurts really if you touch it or are wiping after using the bathroom. Im noticing the pain is alot greater after a bowel movement and that this bump showed up after a day when i had larger bowel movement. Im wondering if this is some kind of strain? There is no other discomfort or itching except for in the spot of the bump.
Has anyone else had this or heard of it? Tweet
