it is one month since I started taking Casodex and 17 days since first Lupron shot. Now I am having hot flashes regularly. Every day when I get up from bed I have an episode like clockwork. Somedays it is very intense and other days moderately strong. Throughout the day I get more episodes at random.
I never had any testosterone blood test before Firmagon and Lupron shots as part of cyberknife treatment for an extra capsular recurrence in 2016. In January 2018, when my PSA was undetectable I had T value of 44. Then when my PSA started rising I recovered T. But the recovered T value hovered around 300 between August and November.
One explanation of why I started having hot flashes a week after starting Casodex could be low normal T. Also the residual hot flashes after last Lupron shot in April 2017 did not go away completely.
