I'm no stranger to pain, in 53 years I've broke both ankles, one of them twice, broke all the bones in my right hand, both my thumbs, both my pointer fingers, put a screwdriver through the middle of my left hand, knee replacement, torn rotator cuff surgery, sawed the pointer finger of my right hand right through the middle of the finger and nail with a band saw to the first knuckle, (learned to use a push stick after that), more stitches than I can possibly remember and the worst pain of all, was trying to pass a 14mm kidney stone for over a month, (they had to go in and get it and it only comes out one way

).
Oh yea when I was a kid I used to get cluster headaches, so bad I would beat my head against the wall in my bedroom as a distraction and in hopes that I would knock myself out.
broken ribs, piece of a wire wheel got stuck in my eye, I remember jumping off the neighbors roof w with a hefty trash bag for a parachute, when I hit the ground from two storys up I'll never forget my Old Man's words as he picked me up and took me to the DR, "0 to idiot in less than 2 seconds"
Yes I'm no stranger to pain but if you focus and have the right combo of pain killers you can tolerate the pain for the most part. Chronic pain is the worst though, day after day with no relief, when I blew my left knee out in '06 I had to work for 10 s weeks just till I could get surgery and accrued enough time off to recover.
Had the platelet shots, cortisone shots in the knees, ankles, shoulders and wrist.
Anticipation is the worst I'd rather have them just do whatever it is they're gonna do without me knowin' when. Funny thing, with all they painful crap I've had and had done to me is the needles that skeeve me and scare me the most.
At 53 I feel like a 90 year old whose been kicked down 3 flights of stairs when I get up in the morning but it all works out by the time I get my first cup of coffee down and stretch out all the kinks.
