10 yrs. ago I had Brachytherapy .My PSA is still elevated at times.I do have urges but I cannot have an erection. I am 70 yrs. old. I take Macardis and colesteral medication and I am on insulin for type 2 diabetis.I also have a pacemaker. I would like to try viagra or cialis at least once . Would it be risky?
