I had cancer 8 years ago and had radiation. The lymph nodes and bladder were involved. The radiation did the trick but I am having a lot of infections and my PSA keeps going up and down. It went to 9.7 and after antibiotics it dropped to 3.5, which kept me out of radiation again for the time being. My question is: Is anyone like this having problems with their bones? Like a lot of pain and knots and stiff? I am interested in knowing if someone else is having this problem and if you know what may be causing it. I thought about bone cancer, but none of my research comes up with anything like this. Could someone help?
