I'd let her know yer Doc wants you to get a 2nd opinion / run some tests but omit his "might be..." comment. No need to put that thought in her head until ye have to.
Best of luck, Mate. Hope its nothing some kinda herbal tea won't knock out of ye.
Even on a low cruise of test, the PSA can go up big-time on some folks.
I know it does for me (I think I get every side effect known, anxiety, insomnia, PSA, screwed up lipids, etc.)
I go back in 3 months for new bloods, so I am off everything now except for Nolva for a month. (Going off has its own sides, massive shaking/anxiety, cant focus, etc).
Some people get zero sides, I get them all. (When I tried Epidrol years ago and got every side, I knew I was in trouble).
(Lipids crash, shin splints, back pumps, liver levels, and so on). I guess I was just blessed
