### Patient: Doctor, I've been experiencing sinus congestion and abnormal involuntary movements. Also, my eyelid has been moving abnormally and it feels like there's a foreign body sensation in my eye. What could be causing this?
### Doctor: Based on your symptoms, it is possible that you have toxic multinodular goiter, which occurs when there are multiple nodules or lumps on the thyroid gland that produce too much thyroid hormone. These excess hormones can cause a variety of symptoms including the ones you've described. We'll need to run some tests to confirm the diagnosis.
