Im an 18 year old, whose been in a steady and committed relationship for almost 3 years. I have a very sore vagina, inside and out, with the pain running up inside to my bladder/womb (im not sure!) Sex is really uncomfortable, especially afterwards. I've been to the doctors about 4 times within the past couple of months, and each time they have said it is probably a bladder infection, and prescribed antibiotics. Each time they have mentioned a number of things like ensuring i go to the toilet after sex etc, which i ensure i do. I am convinced there is something else wrong, i am clear of STI's too. Maybe the doctor is right but is there any way of getting rid of this torture for ever!? Please someone help !
