And just like that, torn meniscus.  Surgery next Wednesday.  According to my doc, none of this due to my recent spike in exercise and appears to be an old injury.

This has been an ongoing thing and I have been receiving cortisone shots in my knee for last two years, one approximately every 4 months.  Not in any pain right now, but doc says I should be with the fluid building-up.  Either way, I plan on keeping the miles up until surgery day and expect the treadmill desk to help in recovery.
