Yesterday I made a slight mis calculation that resulted in a knee that may be beyond tore up this time.. Little life lesson don't be an ass and pick up a tire to carry it around to the other side of your tahoe to rotate them and oh then step on a creeper you left there from changing the oil.. The result a knee you can't bend and a sore back... I've avoided surgery in the past but it looks as if I may have twisted my knee up too much this time to let it heal itself..
