I found this while googling it for you:
Thanks for that Jodie - i went to my chemist and she seems to think its thrush and not a uti so im now using the Canestan 6 day treatment - she advised because im on a long term dose of antibiotics i should be taking inner health plus as well so fingers crossed it all helps she said the burning when i wee is probably more to do with the fact that ive been scratching myself silly cause it doesnt actually hurt to go to the loo it just stings when it gets on the bit ive been scratching (hehe sorry TMI!)

thanks again for the reply
