Hello, You are most probably suffering from geographic tongue. Geographic tongue is more commonly found in people who are affected by environmental sensitivity, such as allergies, eczema, asthma. It may be linked to stress or diets high in sugar or processed foods. Females are affected three times more than males. Causes vary, but may include zinc or vitamin B deficiencies, allergies, and hormonal changes. Geographic tongue is said to occur more often in women, especially during high hormonal times, such as during ovulation or pregnancy, and while taking birth control. There is no known cure or commonly prescribed treatment for geographic tongue, there are several ways to suppress the condition, including avoiding foods that exacerbate the problem. Some get relief chewing mint leaves or sucking on a mint candy or gum during a flareup. Zinc supplements has resulted in a dramatic reduction in the incidence of the condition in many cases. Vitamin B supplements with antioxidants need to be taken by you. Soda might be a causative factor as overdose or may be metoprolol. Hope this helps. Get well soon.
