I have had a pain at the bottom of the opening of my vagina underneath the urethra, there is a small lump there which is the part that hurts...it doesnt hurt all the time but sometimes comes on randomly and often it hurts to urinate.

Ive been to the doctor whose been trying to solve the problem for over a year now but nothing seems to work..I originally thought it was a urinary infection but I'm starting to think otherwise as it only ever comes on randomly.

Its really been depressing me as i havent been able to be intimate with my boyfriend for a while now because of the pain. Noone seems to know what it is, if anybody can think of what it might be then please reply :'(
