Glad you are over your bout with pneumonia...that seemed to be everywhere. My wife had it too.
A simple back of the napkin calculations seem to indicate your current PSA reading of 118 ng/mL to be closely in-line with your doubling time...if one uses your reported 4.9 ng/mL in Apr-2015 and 36 ng/mL in Oct-15.
Let's see... In those 6 months it roughly doubled 3 times. So doubling time is about every two months. So, in December which was 2 months after it was 36 it might be 72. Two months after that, in February, it might double again to 144. Your January measurement of 118 seems predictable.
Good luck Friday.
