A few days ago I noticed a swollen lump in the vaginal entrance area - (skin coloured with inflamation) as if I can feel a tampon slipping out but over to one side. It is quite painful since last night, all of the time, from sitting to walking - like a dull toothache but with a nasty sting - occasionally itchy but no discharge. I could not possibly now have sex or use a tampon. Prior to this a few weeks back I started to develop a fishy smell even after a bath/shower, could this be related? Have I let something go that has become an infection??? Please advise. Many thanks - Lilly.
