Dear Doctors, I have frequent pain knee joints and feet. More or less I can say whole legs and getting feeling that my bones are getting week. Two months back I was diagnosed with critical deficiency of vitamin d and b12 post which I took b12 injections and one D3 injection and I am also taking shelcal 1250 mg tablet. I took test today both b12 and vitamin d3 are fine now but I still have pain in joints.
