LOU, It's great to know you are back to doing your thing again. When I went to my present chiropractor for the first time 25+ years ago, as soon as he looked at my X-rays he asked, "Did your grow up on a farm?" The answer was "yes"
By the time i was 11 or 12, i was weighing in at a rather diminutive 97#'s, or there abouts. I was working in the fields tossing fork loads of hay that you couldn't see me under and picking up 100# bags of feed. By the time i was 13, and still barely 100#s, I was stacking 100# bags of feed as high as I could reach. I mean as high as I could reach, I was stacking feed. Chiropractor told me things like that, while my body was still developing, had crushed discs while they were still too soft to stand that sort of weight. Even after my back started hurting, i was still (a mason by then) unloading lime and cement (lime=50# Cement=94#) from flatbed trucks two at a time for cement and three at a time for lime. I often got involved in helping move fridges and pianos and would always take the end closest to the bottom of stairs or ramp so i had the heaviest load.
Really, when i look back, it was a bunch of foolishness. When my son was growing up, he went everywhere with me. He wanted to help with masonry almost (but not quite) as much as he wanted to run the backhoes and loaders. I would never let him pick up anything heavier than one or two bricks, and then for only a few minutes at a time. He would get sooo angry with me. He now has toys that make all of the machine toys he learned to run on my jobs look verrryyyy small. He picks up two or three ton stones and puts them in place with his hydraulic excavators. Much more sensible. And he ain't sufferin' with any sort of back problems.
One more point: I don't know if i will ever get up the nerve for an operation, but if it is worth anything to you, you have given me atleast a little measure of courage to face it if i ever do get to that point. thankyou for you report and your optimism.
