pimples in strange areas

hey girls, so this is kind of private but I was wondering if any girls have had the same issue here. I have a pimple literally right below my anus and it hurts so much and it's really big compared to a pimple that you would see on your face. could it be possibly bad as it just honestly looks like nothing is there but a bump? i have had this problem before but last time was something that looked like a pimple but this time it doesn't??
