Thanks for all the advice guys. Deep massage is painful for me even when I'm not injured, I'm sure it will hurt like hell right now. I massaged it just a bit earlier myself and it hurt a lot. I can walk, on a bent leg, but if I try to straighten and extend it out a bit it collapses under me.

Will rest it. Tempted to go for a short ride...but I live on a big hill, so probably not a good idea. Thannks again.
