hello,I hope your day has been well

.I have a dumb question to ask.In November a small,painless little bumb appeared in a very personal area.It wasnt a sore and didnt have any puss and wasnt really even red.It was small but to the touch seemed like there was a hard ball under the skin.It went away.But in Jan. it apperared again.Im really worried, can someone please tell me whats going on?
