In most cases AIT is characterized by onset of pain, firmness, tenderness, redness or swelling in the anterior aspect of the neck.[1] Patients will also present with a sudden fever, difficulty swallowing and difficulty controlling the voice.[2] Symptoms may be present from 1 to 180 days, with most symptoms lasting an average of about 18 days. The main issue associated with the diagnosis of AIT is differentiating it from other more commonly seen forms of thyroid conditions.[4] Pain, fever and swelling are often much more severe and continue to get worse in people who have AIT compared to those with other thyroid conditions.[3]
