I use a cane or a wheeled walker most of the time. With the walker I have no problems. Sometimes when I am not using it & may or may not be using the cane, I will take a step with my right foot, (which has been tingly and numb-all the way up past my knee for years) but when I try to move my left foot, IT WILL NOT MOVE. I have bursitis on my right hip, in addition to herniated lumbar discs. This is no fun. Suddenly it seems like my brain cannot communicate with the left foot/leg. If I use the walker, no problem! Has anyone else experienced this?
