hi you have described the typical symptoms taht come out of having low vitamin D levels and anemia both, individually or together i would have liked to know the exact levels of hemoglobin and vitamin D i would also suggest you test for iPTH thats a blood test i would suggest you start on iron replacement and vitmain D replacement also take vitamin B12, folate and calcium supplements when you feel like it after you feel a little better get yourself a bone scan to make sure you dont have osteoporosis if you do, some medicines will have to be added i dont know if you are in india or abroad or what your actual test reports are so please let me know the reports for the exact dosing you may need keep checking your complete hemogram every 15-20 days to know if the supplements are working. i usually prefer to repeat vitamin D only after 6 weeks hope that helps best of luck
