I injured my back way back in Feb. of 08 lifting a stupid 80lb bag of salt at 230am and ever since then its not been quite right. During a spring clean up, while edging my back went out again leaving me on the ground not being able to breathe right for a while. The next time (a few weeks ago) I threw my hip out causing lower back and bad leg pain, It finally felt good unitl Sat morning. We had a patio poured and they showed up at 645am and the dog was going nuts and I ran down stairs to see what the heck was going on and when I got to the last step my body twisted but my foot stayed planted and you guessed it, threw my hip out again. We did some pruning that day and now I'm barley able to walk with severe left leg pain. Ive been to my chiropractor probably 20 times in the last month or two now he thinks I might have a disc problem. For you younger guys....Lift and work smarter not harder NO lifting and twisting (thats what did me in this past winter), stretch every day before going out for 10 minutes, dont make things so heavy you need 3 guys to lift it into your truck, make it lighter and take an extra trip or to to load something up, just common sense things that sometimes we all forget. Luckily we employee 3 people so things are still getting done but last year I would have been screwed big time not being able to mow, something for solo guys to think about! Stay healthy, I'm off to the radiologist for x-rays and back to my chiropractor again.
