<s>[INST] I am an 18 year old female and the pappilae on the back of my tongue are enlarged and sore.  there is also white film that will not scrape off.  Ive seen many doctors.  the infectious disease specialist said he has never seen pappilae look like that and referred us to an ENTspecialist.  my dentist said they are big and hard whereas they should be soft.  The ENT said they are fine and normal.  Two other doctors agreed with me that they are not normal.  Ive tried antibiotics, fungal mouth rinse, different gargles, and had every blood test under the sun.  Do you have any suggestions on how to fix this and give me relief? [/INST] Hello, Thanks for consulting Chat Doctor, Read your query, as you have enlarged papillae on back of your tongue these are circumvillate papillae present at back portion of tongue, this is not a serious condition this is enlarged papillae seen in some patients and this can be enlarged and inflamed due to bacterial or viral condition, poor oral hygiene, vitamin B 12 deficiencies or due to acid reflux don't be worry I will suggest you to consult dentist for evaluation and go for mouthwash like proxy by consulting with your dentist and vitamin B 12 supplements also. Hope this will help you. </s>
