I have a constant pain at my back and neck. And when I used to write something for at lest 1 hour my shoulders starts paining too. I consulted an spine specialist too, he observed and said lack of vitamin D and gave me 3 medicines namely Brigeta 1gm Sachet (once in a week, fm12 sachets, CCM TABLETS (Calcium Citrate Malate, Vitamin D3 and Folic acid tablets) and Rxplus (long list of composition). Told me to get a next check up after 3 months. Its 5 months now, as long as I was taking the medicine I was feeling fine but again all started same. What should I do?
