Sir, I have knee problems. After waking or standing for a long time I feel heaviness in my knees mostly on right side. I got X Ray and ortho check up. Doctor suggested exercise. Please suggest general healthy diet, and other solution as my age is 45. I am avoiding squatting and stairs But worried about it. Vitamin D3 was 16 as per testing 3 months back. Calciflora tab/sachet taken weekly for 8 weeks.
