Hi, dear I have gone through your question. I can understand your concern. Your lump is moving with swallowing. If it is also moving with tongue protrusions then it could be thyroglossal cyst. if it doesn t move with tongue protrusion then it is of thyroid swelling. You should go for ultrasound neck, Thyroid function test and fine needle aspiration cytology of lump. It will give you exact diagnosis whether it is simple cyst, multinodular goitre or malignancy. Then you should take treatment accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using health care magic. Wish you a very good health.
