Madison, what type of seat did you use? I was told not to bike ride for at least 2-3 months after radiation. Did you have much tenderness during and after the ride?
BTW, my effects after radiation (July 30th or close to that) and even with ADT are minimal. I get urgency sometimes and I found that if I hold it back it may go away sometimes. For the first time, I just about pee'd myself the other day, it was close.
I don't think I get fatigue from the radiation, but the lack of testosterone sure makes it tough to get started in the mornings. One thing that I thought i would lose with the hormones is looking at pretty women, well that hasn't happened, they still are just as pretty! Just can't do anything about it.
