I can empathize with you. Had a hacking cough for months and the eventual diagnosis was that diabetes was causing excess water production in my system. My blood glucose wasn't quite as bad as yours but enough to demand dietary changes and some pharmaceuticals. Add cholesterol in the wrong proportions of HDL to LDL and it was a mess. Picked up sciatica just as the pandemic was kicking into gear. Was going high protein, low carb until gout kicked in.

Growing old sucks -- but it's better than the alternative.
