8 mos ago had thyroid us with solid mass 0.7x0.4x1.5, endo said no problem. now i have chronic sore throat, cough, numb chin and facial pain, related?

Hard to say: It could be related or it could be something else entirely. But this certainly indicates that you need to get re-checked! Every disease/condition affects people differently and takes a unique course. Whenever the standard treatment fails or expectation of the normal course of a problem does not occur, (there are always exceptions) then further evaluation is necessary. Good luck. Let us know!

FNAB?: Hi. Did the endo do a fine needle aspiration biopsy (FNAB)? I suspect so, given the dimensions. I doubt any of your current symptoms are due to the thyroid nodule, but I just want to make sure the nodule was evaluated cytologically (and genetically, if your doc does that; we do). Those nodule dimensions are rather unusual, but still, a 1.5'er needs an FNAB. Answer to your question, doubt related.

Not thyroid: These symptoms Don't sound thyroid related. How long have you had them? Sore throat and cough suggest a viral upper respiratory tract infection. THE facial and chin symptoms sound like inflammation and/or irritation of superficial nerves. See an otolaryngologist if symptoms persist. The endocrinologist will follow up on the thyroid mass.

Unrelated: Unrelated but serious symptoms. See ENT doc for exam/recommendations.
