Can a depletion of magnesium cause muscle aches?

Myalgia: The classic muscle symptoms of magnesium deficiency are muscle cramps, muscle weakness and muscle fatigue. Loss of magnesium occurs from excessive vomiting and diarrhea or diet severely lacking in leafy green vegetables. Taking magnesium tablets corrects the deficiency. Muscle aches generally are caused by other problems such as polymyalgia rheumatica. A rheumatologist would be best to consult.
