I have sores on the side of my tongue that really hurt. what can i do to get rid of them? or prevent them from appearing

Canker sores: No one knows exactly why canker sores occur, but they are often secondary to an infection somewhere else in your body, or to stress, or to eating too much spicy or acidic food. I prescribe a liquid concoction that my pharmacist compounds for me; your dermatologist probably has something similar. Prevention involves discovering the cause and eliminating it.

Decrease acid: Many of my patients with mouth sores drink or eat a lot of acidic foods or beverages. I have them stop drinking coffee, tea and sodas and stay away from oranges orange juice tomatoes or other acidic foods and drinks. I also have them rinse their mouths after each meal with maalox liquid. They also rinse their mouths before they go to bed. If this does not help see an ENT doctor for an evaluation.
