Hi Sailor, thank you, for replying, I have been drinking Cranberry juice, and having Urals but neither are helping, I know a chemist I will ask him to make me up some Potassium Citrate, I went along to the nurse and they thought it sounded more like an infection and they tested me and it was positive,so although I still have radiation induced cystitis,the pain is a lot better now I am on antibiotics..
