I blew out a knee installing sliding doors all day on a tile floor without knee pads a few years back. Had to get drained and all... Now every so often, especially on rainy days, my knee just hurts like hell... Two years ago I completely wiped out my back. I have two herniated discs in my lower back which kept me out of work for a few weeks... I was doing the Chiropractor several times a week, but it just didnt seem to help much. I'd feel like a pretzel when I walked in the office, and I'd feel great when I walked out.. for about an hour.
Then I was in agony until the next visit. If I wanted to go for a car ride that was longer than an hour, I'd have to schedule an appointment with the doctor right before... Finally I gave up on the bonecracker... I bought an inversion rack off Ebay, and I swear I've felt great since. I dont use the table type, I use the one that mounts in a doorway, and you swing yourself up into position like a monkey. A few twists and stretches while upside down, and it frees up all the spinal compression that gravity causes all day every day. Occasionally I'll overwork my back and feel the nerves getting pinched in my spine. I hang on my rack that same night, and wake up feeling great.
