Nothing is 100% - but in experienced hands, the risk of surgery is low. The gland should not return if a near-total thyroidectomy is done by a thyroid surgeon. He will need lifelong thyroid replacement medication. The indications for thyroid surgery are a suspicious biopsy or an enlargement causing pressure symptoms (trouble breathing/swallowing, hoarseness,etc).
Dr. Lupo, I had the left node of my Thyroid removed and I am on day 5. I am feeling less pain daily. I take thyroxin in the morning when I get up at around 0600 or 0630 am. Around 2:00 to 3:00 pm. I begin to feel like I have sinus pressure around my eyes and head and just generally feel like ****. It is hard to explain, also have a small headache, just don't feel well. Only pain med I am taking is Aleve. Any suggestions?
