I've had them in the past. Seem to disappear after a while, although one got quite pussey and had to be burst.
It this time, it seems to move about a bit. Shuffles forwards and backwards. Goes for a few days then comes back.
It's reared is ugly head quite painfully today, and is now lightly bleeding.
Does this sound like a bartholin cyst? Should I leave it be?
Or something I need to get 'seen to'?
