you cannot see your eustachian tubes from looking in your mouth. besides the inside diameter these little tubes that run from your middle ear to the back of your throat is about the size of a hair. without an examination there is really no way for me to evaluate this "food layer" that you claim to be seeing. i am sorry but you will need to see a medical provider -- someone who can examine you. one possibility would be that you are seeing a "tonsillith" or tonsil stone. try looking this up on the internet. another possibility is exudate which may be improved by gargling with warm salt water. again without seeing it i cannot make a blind guess as to what you are seeing.
how can a food layer which formed in my throat (eustachian tube) be removed? . yesterday i ate noodles (the gravy was made with milk salt pepprica origano ) and then i immediately slept. today morning there was a layer formed in my throat (i think in my eustachian tube) and whenever i try to remove it i choke. please give me a solution.
