Oh, I have brought up several issues that happened in January or just before as possibilities. Not the least of which is physical therapy for (yet another) neck problem that cropped up late December after spending the whole day “looking down” at a clipboard. (You have to understand - lots of neck problems also 20 years old - stemming from auto accident on Halloween 1996.) I still have my suspicions. PT helped that small issue but did it lead to this?
I wish I had a better answer for your condition. :-(
I’ve been up too long, for some reason I was thinking of this song reading this thread again (perhaps humorous, or just me being silly)...
