Jeepers Pan, I've never seen anything like the pics in your post. Does that hurt, or is it numb?
Numb first, then pain. Not the tingly, blood coming back into circulation pain, another kind of pain. Doesn't do to let them get blue; tissue dies off.
When numb, better trigger control (and that says very little about my shooting skills); once the pain set in, couldn't squeeze the trigger anymore. Then, warm up -- THAAAT'S when the tingly pain sets in.
Pain in the ASS. (Hand). I can stimulate circulation by firmly stroking arm from elbow down to hand, literally pushing the blood in/down. Takes a few minutes, though. And is then offset by the cold.
My father had it too. He thought it was because he'd broken his fingers so many times -- auto/truck mechanic all his life. Evidently not, although the link said nothing about heredity.
But! I found these .....
Sending link to Gunsmith. My birthday is next month. And I'm going to be 59. And everyday, I feel it more and more. At 39, I had more relative muscle-mass than most men do at 50. Or most of them at 39, for that matter. I don't know what happened (well, yes I do), but I don't like it.
My prayer: Please God, if it is Your Will that we have to stand up for Your Way, give me strength.
I'll be getting some, to see if they work.
