I suspect I had the perfect storm brewing here with major stress and anxiety in my crappy life, coupled with exercise after having been so inactive for years. I cannot do much about the stress but I will need back off the gym for a bit. I wasn't doing much, some leg exercises and 1/2 mile daily, but evidently even that was too much for my poor damaged body. I still hurt like hell but it is important to keep my spirits up. Yesterday I was falling into the abyss and that is a scary dark place to dwell.
