question: Lower back pain unable to put pressure on legs to walk. 3 weeks ago I was lifting my dog into the car. I got a sharp pain in my lower back..went away in about two days. Today I was lifting my two year old into an inflatable tube, While setting her down I had the same pain but on the mid right side of my back. This pain continued all day. Then while bending down to get a dish out of the dishwasher I got a horrible pain in my lower back. The pain knocked me to the ground. My husband had to help me off the ground to the bed . Since then I have not been able to put pressure on my legs to walk without horrible pain.
