Hi , I am 40 years and encountered with orthoathritis . Doctor told me Cartilage between the joints has gone . I am applying some ayurvedic oil to massage my knee and doing the stretching exercises along with pranayama and sudharshana kriya . My office is 20km away from my residence , I travel 40kms up and down everyday . Please can one tell is it safe driving car or not ? . Can anybody suggest with home remedies and care to be taken.
