I am 16 years of age and yesterday discovered a large lump on my inside lip of my vagina, i then discovered it was probably a bartholin cyst. I have done some research on the internet, however there is no information for what i should do if it is painless. Do i need to see a doctor? The lump was around the size of a grape but has gone right down and now one side is just bigger than the other lip. How do i get it back to normal size ? I know it is not infected or an STI as i have only had sexual relations, not actual sex. Please help!?
