I have multipul little white soars along the lower part of the inside of my mouth, and I have tiny soare bumps all along the side and underneith of my tongue. It stings to eat most anything, brushing and using mouthwash. They are not bleeding, but they are very soar. I recently had my tongue pierced and a friend who also had hers done, said the soares on my tongue were similar to the ones she got durring the healing process of her piercing, but the white soars inside my cheeks and under my tongue were not. Any advice?
