question: Hello doctor, I have swelling in the neck and tested in the laboratory about three years ago. They say I have a problem with my thyroid and I need to consult a doctor. Unfortunately, we do not get a chance to go back to the hospital again because of a lack of money. I am 17 now and my neck is still swelling, I do not feel any symptoms as of now. The last doctor who checked my neck says it is a non-toxic thyroid problem (but they did not tell what my illness is, because it is just our school medical. better to consult a doctor). Is there any recommendations to prevent my neck from swelling? What are the foods and activities to control the swelling? Is there any thyroid home test I should try to identify how is my thyroid? I will consult a doctor if the situation is totally fine.
