hello and welcome to hcm forum CC,
i am glad to posted your query, first of all i would like to inform you that your tongue has abraded a little due to the friction with is produced while sucking and chewing the sour candy, excess of everything can harm.
I assume that even your palate
might have peeled a little.do not worry, the tongue will heal completely in 3-5 days. Avoid spicy and sour food for a while , as the tongue is still peeling.
besides, i could not get that your cheeks have a film which probably you can chew off, i recommend you to visit your dentist
regarding the same.
i hope i answered your query,
i wish you good health,
