I have had water infections for 4 years. I have had tests done at various hospitals where nothing has been found. I have been on antibiotics constantly and over the past 6 months I can't get infection free. I have looked back over my doctors notes and realised that i didnt get uti's until having the coil fitted in march '06. My first uti was in oct '06 and I had the coil taken out in jan '07. Could there be something left inside me from the coil that could be causing the uti's?
