My bones have been feeling weak for the last few months. Legs, arms, back, every bone is weak, I can feel it when I walk or lift anything, it feels light and weak, no strength. I checked vit D, it is 25 ng/ml. Should I take vit d 60k? How many months? It is causing me problems in daily life, as my bones feel really weak. I have calcium foods like milk, curd, etc. Also, will homeopathy medicine like calcerea phos 6x or any other help to improve it? What do I do?
