Hi Susan,
My husband is 2 1/2 years post treatment, but I can remember it vividly. He only had radiation too and I'm not going to kid you, it's tough. But you CAN do it. What we learned the hard way was to keep consistant on the pain meds. Set your alarm, whatever you have to do, but don't let the pain meds wear off.
My husband has a very physical job and he was able to work for about 5 weeks into the treatment and then he had to take a break. It was just too much. But then again, others here have been able to continue working. I think it depends on what type of work you do.
Best of luck to you. Please remember one thing....there is light at the end of the tunnel. My husband is 2 1/2 years cancer free and doing great (knock on wood)!
Take care,
Shelley
