Hi Chris J,
Sorry to hear that, Chris. As others have said, it might be just a blip, but it's a bummer even thinking that you might have reached your nadir. It can increase your anxiety (even more than it already is) before every future test: will it stay at the new level, or will it have increased again, and if so, by how much? In spite of advances in prostate treatments over the years, there is still so much guesswork involved. Even the medics can't say what is going to happen next, or when. Living with this uncertainty takes its emotional toll.
I hope you can help to distract yourself from all the worry (and 'what if's') by spending time with the people you love.
Best wishes,
JedSee.
