Norm, You could be like me. Barely able to move the left hand middle finger, you know the insult finger. Then the elbow on the same arm very stiff too. I taking the meds and just powering through the pain but does make difficult when you're left handed. Finally after 2 weeks I can now close my hand most of the way but still can't just pickup my impact gun without using the right hand. Sure glad I got an engine crane. It look stupid for to be using it to move around 75-100 lbs engines but the only I can anything done.
Just I knew what I did to get in this shape but I don't.
I do understand about the leg problem and how affect your ability to work though as I got weak ankles and I am bad to sprain them if don't wear my support shoes. If I do I on clutches for a few weeks. Again that why prepared my shop for being handicapped.
