So last week I had the SpaceOAR rectal spacer and fiducial markers inserted.
My Radiation Oncologist also put me on a prophylactic 50mg daily dose of sildenafil (Viagra) starting 3 days before treatment and continuing until the end.

Had my simulation and first radiation treatments for my Gleason (3+3) this week. 2.5 Gy X 28 treatments = 70Gy in total on a VMAT linac. So far so good. Treatments are less than 15 minutes in total, probably closer to 10 minutes
The only thing I have noticed so far is that my urine stream keeps getting worse. The doc says that it's somewhat normal due to the biopsy, SpaceOAR and fiducial markers irritating the prostate. He says that may get worse when the full effects of the radiation treatment kick in and cause further irritation. Might have to go on Flomax if it gets much worse...
