Hello, there are many possibilities for this constellation of symptoms and signs. it could be a viral syndrome
, acute inflammation of the thyroid
, and unlikely something more significant. I think that the best thing you should do tomorrow AM is reach out to a doctor, like the covering doctor, and get seen by the doctor so he/she can do blood work and examine you. You should also have your Thyroid blood levels checked. In the meantime, for tonight, as long as you have no history of liver
disease, you can try Tylenol
650 mg X 1 dose today.
