I was bedridden for a while. I went to the doc and got my Xray and MRI done. The results are fine and I have a normal back. It has been three weeks now and although, the pain has subsided, I do have pain when i lift my leg or sit in a position for a while. But, what I am worried about is that when I sit in a fixed position for a while and then stand up, my back takes a while to straighten up. Is that normal while recovering from a back problem?
