Last year my wife got chicken pox after getting the chicken pox well, We saw that her throat has a swelling on the left side, then we went to a thyroid Dr. He told that it a thyroid nodule and it occurs due to iodine deficiency, lot of fluid was gathered in her throat and he said that there is no permanent treatment for this besides getting the fluid out by a treatment after every 6 months. So I want to know that is there any treatment for this? And why it occurred after chicken pox? Do we consult to a ENT Dr. Pls help because that is appearing again and looking very bad on her neck. We got some test done including Anacin and it was cystic colloid nodule. Do we have to get surgery done? What could be the amount of surgery?
