Another suggestion Sara that really helped me, I was 12 years with incorrect diagnosis, is Locoid cream. It's available online and not too expensive. It's a local anaesthetic and I will warn you it stings and burns like crazy when you apply it but the relief is wonderful. It only stings for seconds and then everything gets beautifully numb. Once things are numb you can apply a little more without the stinging.
My GP initially gave it to me on prescription just so I could get some pain relief. My gynaecologist prescribed it because she insisted I had vulvadynia and I disagreed. I mentioned using Locoid so she said to try it again to prove her diagnosis correct - vulvadynia is nerve pain and a local anaesthetic wouldn't stop the pain. Obviously it worked and proved her wrong!
Just a suggestion because the GP and gynaecologist told me to use it as often as I wanted a break from the pain. It really seemed to calm things down after a while, particularly the urethra issues.
