I got one little

I got one little blistery type bump on my vag. its not on my vag. more like the top where the hair grows. i have been checked for STD's blah blah blah. i have nothing . I haven't been with anyone else and i know alot about STD's and what they look like . So that isn't it. I thought it was a hair but i cant find a hair in it. I had a similar one come in close to it and it actually was a hair . I removed the hair and now the other one (the one i mentioned in the beginning) is still there. It doesn't hurt , itch nada , but it feels weird when i feel down there. I have popped it , almost like a pimple but it came back . Maybe the hair is deep inside and i cant find it because i have actually gotten these type of things alot but they are ALWAYS ingrown hairs or something that has to do with a hair . Should i try to pop it again and dig at it ? i know sounds weird sorry about that but idk how to get rid of it .
