Sprained the heel of my hand, so its not actually the tendon, more like the ligament.
Not as horrifically bad as I thought, Just have to let my hand rest, not strain it, stretch the wrist and fingers, but not torquing them the wrong way, and ice massage it.
2 weeks off and then be careful for another week or so... and with the stretching, all should be good.
So lots of stretching and Core for the next few weeks.
Thats what Im saying. Lets see if I do it.
