OK... Now, I have had several injuries to my hands now.. Murphys Law.
The first was three trigger fingers, and the last one, left me with a cord in my palm.
Now, that was alright for a bit, until I got a puncture wound from a nai ontop of my left hand, where I have the cord. I had surgery, because, there was debree left in the hand. Oh, low and behold, I now have no feeling in that area, and , best yet, my cord has now turned to having a big nodule in the middle of the hand. Then, as I have horses, I went out and knocked that same finger against somthing, and the whole finger swelled up, and the nodule got even bigger, and , then, I could not even straighten my finger out.
Now, I am a firm beliver, that injury to the hand, just gets this thing in motion, and gets it on a roll. I have seen too many people in here, that have had tigger finger, and carple tunnel. But, this last injury of just slapping my hand down on a surface, and it causing such damage to my finger, and then the result of just the next morning of a nodule next to my cord, tells me, that, I just have it, and there is nothing I can do about it, and also, injury to the hand just makes it's progress faster. It seems to get the whole thing going Each injury I have, seems to get the Dups, going more, and more full blast.
You know, I could give up what I do, as raising horses, but, I am not going to do that. But, I find it harder and harder, to use my hands.
Anyway, I have found, with each injury to my hands, my Dups get Worse. It aggravates it so much.

Hope this helps with any resurch....Randy
