###Human: Why are there white spots inside my cheeks with sores on tongue and lips? ###Assistant: Hello. I have gone through the photos you have provided and noted the sores and white spots inside your cheeks. There are a few explanations for those: 1. Eating or drinking hot foods, drinks, drinking carbonated drinks.  2. If you have experienced flu-like symptoms, it is due to acute viral infection. That might take a few more days to get completely healed. Avoid drinking too hot foods or drinks or carbonated drinks. Keep good oral hygiene. Apply oral antiseptic four times daily. Apply Glycerin of Borax on the sores. If they hurt, can apply Diclodent (Diclofenac) spray orally. If no improvement, then, should consult further with ENT specialist.
