In this article we discuss about the calcium deficiency symptoms in Urdu. A calcium deficiency can also cause numbness and tingling in the hands, arms, feet, legs, and around the mouth. Fatigue associated with calcium deficiency can also cause lightheadedness, dizziness, and brain fog, which involves lack of focus, forgetfulness, and confusion.
