Hello, last month I had very chronic pain in my Lower back and later I was not able to sit, stand due to pain but after some days the pain got reduced but I my left leg and and hand feels very weak while walking. Sometime I get little burning sensation in my upper back and in neck also I get stiffness. Now I am able to do exercise and yoga but still I feel my left leg very weak compare to right leg.
