Elaine,
This happens to me occasionally, especially if I've been waiting to void longer than I normally would, and especially if the reason that I've been waiting to void has something to do with emotional stress in my environment.
Everything is worrisome about this disease isn't it? Especially when a lot of these strange nuances about urinating seem to have no clear answer.
Tell everything to your Doctor so that he can be on top of any issues and please keep us posted with how it is going. I noticed that you haven't had a lot of response to this question, so it may just be that this is not a common issue.
Take care and please keep talking,
PS...the reason that I am not as responsive as normal is because I am out of town for a week for the birth of my new grandson. I will try to keep an eye out here, but should be back to normal after next Wednesday...
Best regards,
Rosemary
