Hi Molly Mae ,sorry your in this position.My husband Gary was diagnosed in December 15 with similar stats ,PSA 23 Gleason (4+5) spread to lymph nodes .
Gary had 6 sessions of chemo which thankfully went without problems still managing to work everyday .He is now on the stampede trial and his PSA has been undetectable at <0.01since May 2016 .
Hopefully your OH will have similar results .garys main symptoms now are fatigue but still continues to work 5 days a week in a manual job just a bit slower . Our life is still good if not different and manage to go on lots of holidays .
Good luck and keep us updated .
