After foolishly lifting a huge weight, I managed to herniate my L4/L5 disc. My doctor instructed me to wear a brace to stabilize my back. I bought several of these and found they were uncomfortable and none of these allowed me to walk without pain.
I was about to give up until I was fortunate enough to discover this belt. It seemed too good to be true, but honestly, this belt allowed me to walk again with minimal pain for an extended period of time.
Needless to say I was elated and relayed this to my doctor when I saw him. He too was impressed. now i also use it for with ease
