My father (62 years) had cervical spondllysis but in aiims delhi doctor had told me that it is only defficiency of calcium. We have improve the diet and after that that problem was cured. But since 1 year his legs and hands always have ache. He is now feels pain always and becomes unable to walk so long. I had advised to do the x-ray and blood test. I have done that. Those were also fine. Now please advice me what to do now.
