Hello PepeDee, welcome to the forum. Glad you found us.
I did a bit of searching through old threads to see if I could find anyone with problems similar to yours. We get reports of problems with lymphedema (mostly swollen legs) after surgery where lymph nodes were removed, and a number of guys complain that the Jackson Pratt drain installed during their surgery overstayed its welcome, but I couldn't find any discussion that matches the full particulars of your problem; in particular, ten weeks is a long time to be putting up with this sort of problem.
You said you were waiting for an appointment to get your clogged drain replaced. Do you have an appointment and are waiting for the procedure, or are you having trouble getting an appointment? Will your urologist be installing the new drain or some other surgeon?
I'm not sure how much actual help we can be with your problem but we'll keep you company while you work your way through it. Do keep us posted on new developments; maybe your thread will help the next guy with a similar issue.
Here's a link to the discussion I found that seemed the most relevant. Bear in mind that none of the posters are medical professionals -- just guys sharing their experiences -- and the ones who talk the most aren't always the ones who know the most. Also bear in mind that the thread is seven and a half years old.

It will return results from all the forums (not just prostate cancer) so a search for "lymphedema" returns results for breast cancer and lyme disease as well as for prostate cancer.
