My husband, Adrian has had this problem for a couple of years. We thought that some of the problem was from having Prostate cancer. He had some radiation after the seeding. But from what I'm hearing it also happens with Parkinson. I wish we could solve the problem but.....oh well.

I suffer the same problem with my bladder it started about 2 years before my pd was diagnosed I also suffer with bouts of overspill diorea even though I have a small but daily visits to the loo. Taking movicol daily but even this does not solve the problem fully, I does affect my ability to travel even locally. This is probably not much help only to show you are not alone.
