Hi, Can calcium and vitamin D deficiency lead to dizziness?. I am having vitamin D deficiency but my other reports are normal. I am having dizziness from last 5 months and unable to diagnose the real cause. I had vertigo test/spine test/ecg /utrasound/complete body checkup. As my all reports came normal but still I am suffering. Its difficult for me to go out as i walk much I get foot pain and knee pain as well and after that I feel dizzy and off balance. I feel so weak from inside. Can anybody suggest what should I do.
