Hi, My age is 26 and I am from India .3 weeks back I suffered from acute pain in my left hip joint and knee. My doctor told me to take 60000 IU Vitamin D Tablet daily for 10 days. After that take it once a week for 6 weeks. My pain has improved a lot but I had back pain as well , so I went to doctor again. He suggested me too continue with the medicine as back pain is also due to Vitamin d deficiency. Has anyone else also felt the same. Thanks
