Since last Tuesday, I am having pain in the back. On Wednesday and Thursday it came down to both the legs and on Friday it went back again to the back. On Saturday I consulted a doctor and he suggested to get an x-ray done and told it might be vitamin d3 and vitamin b12 deficiency. In the x-ray nothing came. The pain has been increasing for the last 2 days. I am also undergoing physiotherapy but it's of no relief yet. On the first day it was fine but on 2nd day it didn't make a difference. Please suggest me what needs to be done.
