I have a rather large inflamed lingual follicle on the back side of my tongue . It s far enough back that it s tucked under the right tonsil when the tongue is relaxed, but when the tongue is extended to the maximum, its just at or in front of the tonsillar arch. It seems like a rather large flap with a white crest. It doesn t seem to be painful. I m extremely worried about it being a tumor or some sort of cancerous growth. I have an appointment at the ENT tomorrow, but I can t even function, and keep looking at it and information on the internet... I m very nervous.
