I too suffer from Lingual Tonsillitis not to many doctors have seen this apparently its quiet rare.
I had my tonsil removed as a child so my family doctor didn�t think it had to do with tonsil at all, I was treated for Strep Throat and different infection but nothing worked, so after 3 days of antibiotic and Alot of pain (hard time swallowing, massive ear ache and a muffled voice) I went to Emerg where I was admitted and ended up being hospitalized for 2 days in ICU (due to air way restriction) and spend and other 2 days in the hospital, (they originally thought it was an infection of my Vocal cords) but after several tests, and scans, Demerol, steroids and two different kind of antibiotic, it was determined that it was Lingual tonsillitis and this is when I was diagnosed with it. They told me at that time I was lucky I came in. I could have died in my sleep because of the way my air way was inflamed.
It�s been close to one year and i still have an enlarged lymph node and suffer from mild pain in my throat and ears daily, I get checked couple times a year to keep tract.
I was told that there�s not much they could do about it.
Up here the Doctors won�t touch you since there a really high risk of bleeding out while removing the lymph node at the base of the tongue, and laser method is still kinda iffy. I have learnt to live with it but I�m hoping for a solution soon, i wish i was my old self again but i'm hoping with time it can happen.
