Does Magnesium Deficiency Cause Recurring Chronic Urticaria?

Hi, am suffering from chronic urticaria from past 6 months. It occurs mainly when i eat tangy or spicy foods. It even gets worse in hot weather.i am currently taking antihistamine (Cetrizine) for the same. But its effect is only temporary and stays for 8 hours.I had the similar problem 5 years before and had taken tablet Elina as per my doctors prescription and the problem remained for 6 months and then faded. It has again occured to me this time. Can Magnesium deficiency be one of the cause? Also can u recommend any treatment or medicine?
