My father is having extensive joints pain in knee and shoulder. He is suffering with this kind stiffness problem since 2001 and when treated in 2005 was diagnosed deficient in
Vitamin D and was given two injection of Vitamin D and he got recovered from then problem. In 2015 also when he was having this problem he was again tested and found to have vitamin D3 less than 7.5(less than the given parameters) and he was given tablets of Vitamin D and was temporarily recovered as he did not completed the course of the Vitamin D3 as soon as he got the initial relief from it. But Today again he is having the joint problem and he is not taking any tablets for Vit. D3 and Cod
liver oil(I had asked him to take). He doesn't drink milk from quiet a long time and he is a vegetarian. He does not want to take medicines but wanted to intake this deficiency from food only. Can some one please suggest what could be done in this situation. How he can improve upon his health.
