Went to bed last night and was fine. When I got out of bed this morning my right knee was in serious pain. Very stiff and hard to straighten out and just a little puffy. feels like a strained ligament but could just be inflamation. So I'm straight legging it around today. Feels like a 3 or 4 day recovery (at least) injury.
Now I've popped my knees many many times over the years playing sports but this is unusual. I can't remember anything I did during the day yesterday that would account for it. I can't believe I did this while sleeping!
Of course this means I can't do much today either. Even going down the cellar stairs to play in my woodworking shop seems unlikely right now. Bummer...
