Yep, it's pneumonia. Because of recently developed high fevers and an enduring satanic cough I finally capitulated and visited my local clinic this afternoon. The good news is that my diagnosed condition isn't severe enough (in that it's not affecting my cardiac functions) for hospitalization. I'm to remain in bed for at least 48 hours and stay newly doped to suppress my violent cough -- neither of which will interfere with my reduced, December writing schedule -- and of course take antibiotics.
That's the latest, and the last, I hope. I'm ready for 2017.
