The bone scan doesn't detect prostate cancer directly, but it detects recently growing bone, because mets cause bone changes around them. If you've damaged or broken a bone in the last 6 months, it will show up on the bone scan too as it's healing. So does arthritis (although bone mets don't tend to be on joint surfaces where arthritis is, so that's quite easy to distinguish). So falling off your bike could be the cause if it caused some micro-fractures. If there are just one or two suspicious spots, they will get more detailed scans or X-rays to check for mets specifically.
The reason to delay the bicalutamide is that it will impact the PSA (and they don't want that until they have a second PSA test and can see if/how it's changing by itself), and it would reduce the sensitivity of the PSMA scan.
By the way, if you were interested in Brachytherapy, you need to ask an oncologist who does it if you're suitable. I would not take the word of a urologist on this.
I had what might be a similar diagnosis to you, and I had a combination of external beam radiotherapy, and HDR brachytherapy. (It's all in my profile.)
