Hi thank you all for the advice.

I have been wondering about whether I am going mad about this because everyone that I ask says my tongue looks normal and the doctors says it looks normal. The CT scan came back clean, there are no lesions or anything but it is my tongue and I know that it is enlarged. The muscle on the floor of my mouth is often tired because have to retract my tongue to fit it behind my teeth when I close it. I am very sure that my tongue is enlarged, I only have trouble getting the doctors to acknowledge so.

Should I push for a biopsy? I have suggested it to one doctor but he said he would not know which part of the mouth to sample because there are no visible lesions.

And what are you guys' opinions on the effect of garlic against cancer? allicin seems to slow down and kill cancer cells and anecdotes I found on forums seem to suggest that they do work.

EDIT: I am going for a food allergy test tml to see if the swollen tongue is due to an allergy, as proposed by the doctor.
