Oh Kazbah, you poor thing.

Without wanting to get too graphic, have you had a look at it (I know that can be difficult whilst PG! LOL). Is it hardish and red/purpley looking??

If it's increased in size like that and you're not getting any relief by other means, or it looks the way I described, then make sure you go to the Doctor and get it looked at. I really do sympathise. It's just the pits......the pain is shocking.
