<s>[INST] i have had what i believe are enlarged papillae on the sides of my tongue for about a month now, they come and go and switch sides often. it feels like i have a popcorn kernel stuck to that particular place each time it happens. ive looked inside my mouth several times and found nothing but a slightly swollen papillae (always on the sides, never in the center of my tongue). i am a 25 year old female and i do smoke , but the bumps did not start appearing until i began to try to quit smoking about a month ago. i also have hypertension and take metoprolol tartrate 50mg 2x daily to control my blood pressure which has been good. i try to stay hydrated but i also drink a lot of sodas. any ideas? i have had the current bump for 5 days, it isn t painful, just bothersome. [/INST] 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 have resulted in a Chat Doctor.  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. With  </s>
