I have a severe shooting low back pain that travels down my legs affecting my thigh and ankle area. The pain is very severe and increases with climbing stairs or walking continuously for long time. The pain subsides when I apply hot water compression but only for the time being. It has started from nearly a month and I feel that the pain was mild in the beginning and is increasing day by day. I am unable to sit for studying as it makes it really difficult for me to concentrate with the pain.
