The post-con lurgi is on the downward slide now, which is good. What is interesting is while the cold was at its worst, I only had very minor balance issues, needing the walking stick only in the evenings. As the cold has lessened in intensity, my balance has gotten worse. I'm currently at the point of using the cane continuously, taking small shuffling steps lest my balance/legs give out. But I'll certainly be bringing up with the Doc that, while the cold was at its worst, my balance issues were lessened.
It may be co-inky-dink but it's certainly worth a look.
