Started week ago. Tenderness and sharp nerve pains when going to the loo. Started taking Cystopurin and drinking lots of liquid. Drinking cranberry and even tried Actimel as I thought that would help. I keep thinking things are improving than it comes back again. Yesterday had no sign but came back in the night and left me in pain for an hour or two after going to the toilet. Had another Cystopurin and Actimel. Pain went off but going to the toilet still feels zingy. I have been trying to avoid going to doctors and going on antibiotics, especially as I am due a routine blood test on Monday. Has anyone got any ideas? I would be so grateful.
