I have had almost continuous cystitis for the past six months which will clear with over the counter medicines but it soon comes back again. I have had tests at the doctor but the results always come back as "nothing significant found".
I have assumed that this is nothing to do with the PD which I have now had since 2004, but guess they could well be related.
I put up with it, but it is really awkward sometimes when desperately searching for facilities and does become very uncomfortable.
Would be interested to know what the urologist thinks and whether it is related.
Good luck and hope you can make some progress with your mum.
