I agree with fogball. Looks like you and I had our surgeries at the same time. Currently I'm off my feet on the bed more than I would like, and walking less than I would like, but that's because my urine color has been deep pink more often than it's been clear, and my discharge instructions say if that happens to drink more and take it easy. So I've been balancing the need to exercise with the need to rest and heal. I also confirmed with my doctor's office that this is the right move, and I suspect you are having similar issues. Everyone's case is different, and everyone heals differently. The guy that runs the local PCa support group told me he had his operation on a Monday and was back to work on Wednesday. But he also said he had zero abdominal pains or cramping, whereas it seems like I've had it since I woke up from the anesthesia. I would say as long as you have discussed your individual situation with your doctor, then the best thing to do, as usual, is to follow your doctor's instructions. Having said that, I also believe there is nothing wrong with asking lots and lots of questions, so that if nothing else you can adjust smartly as your situation changes.
