sore tongue, feels tired

A week ago my doctor said i have post partum thyrotoxiosis, (an over active thyroid). My main symptoms are anxiety, tiredness, palpitations and a lump in my throat. Since i have seen my doctor tho, my tongue feels absalutely sore, it doesnt have sores on it, but it feels over worked like ive been licking stamps all day. (only way i can describe it). Sometimes my jaw gets sore too. I would like to know if this is a symptom of the thyroid or if i should go back and see the doctor
