Blew a disk out of L4 and L5 20 years ago. I was carrying a speaker for a band job. The pain went into my foot and I have lost much of the feeling in my big toe. I was in so much pain, ended up emergency surgery. Some tips for other back pain sufferers. Take your wallet out of your back pocket, it miss alines your spine siting on it all day. In the morning while still in bed do leg curls (just lift your knee up to your chin several times) one knee at a time. Plus my biggest help mostly after surgery was to swim. Water aerobatics is OK but just do slow laps in a pool doing the simple breast stroke. Nice long reaching slow and easy 20 to 30 minutes 2 or 3 times a week. On the 3 time i went I ALL my back pain was gone. Still cant feel my big toe like i use to. As a general rule most surgeons wont do surgery unless your pain radiates down into the lower leg and foot. At this time your potently cause nerve damage. And surgery is your only hope.
