Hello Sir, No need to worry, it’s absolutely normal. Thank you

Absolutely normal structure of tongue, a type of tongue papillae present physiologically at back part of tongue. They appear to be normal in size, shape and colour.  So,  they are in their physiological state. No pathology is evident.

Normal thing not to worry They are circumvallate papilla one of the many taste buds present on the tongue Normal anatomic structure

No need to worry as they are normal variation in ones mouth. They are one of many taste buds on your tongue normally known as papillae . U don't require any medicines for this and stop looking at mirror and being cancerophobic. Regards Prof Dr Rohit Malik Director Delhi Dental Hub www.delhidentalhub.com

Not to worry since these are the papillae, normal structure of tongue. Hope u had taken 15 days antibiotics with doctor consultation

These are normal structures present at the back of the tongue. There is nothing to worry.

As per the image...there is no abnormality as such...only the pappilae seems to be little larger which is normal...but as you said that you have vit b12 deficiency so you might have pernicious anaemia which does affect the tongue....so whatever treatment is being given to you for the deficiency please continue with that as per the doctor so that no further oral manifestation occurs
