I have a bump next to my hooha and I have no clue what is it.

So a little over a month ago, while in the shower I felt a little bump by my vagina/butthole that I initially thought to be an ingrown hair, so truth be told I left it alone because I was scared if I tried to pop it I’d irritate it. Now it’s still there, it no longer hurts but it makes walking and sitting extremely uncomfortable cause it feel like the fabric of my underwear is still irritating it occasionally. Please help, I need advice on how I should handle this and if I should spring cash to go get a check up.
