Hi.. Can understand your concern.. As per your complain the large pearly papules on the back of the tongue are enlarged circumvallate papilla which contains taste buds.. Due to fungal infection there is infection and inflammation in the papilla leading to their enlargement.. The skin tag kind of thing at the side of the Tonge can also be enlarged papilla due to fungal infection.. As you would be taking treatment of yeast infection like nystatin mouth wash and oral fluconazole or itraconzole and increased intake of probiotics like yoghurt and garlic in diet as the yeast infection will clear off the enlarged papilla will also regress in size.. What you can do as for now is to do warm saline gargles and maintain a good oral hygiene.. You can drink plenty if cold water to prevent dry mouth and such on ice pops for reducing inflammation of the papilla and help in regress in size.. Hope your query is solved.. If you find the answer helpful please write a positive review and click on find this answer helpful as a token of appreciation.. Thanks and regards.. Dr.Honey Nandwani Arora..
