If you have a nodule in neck, you should get it evaluated. The usual tests we do are an Ultrasound
neck and a needle test (FNAC). It could be a swelling in thyroid
or a lymph
node near your thyroid.If its not growing, it is not an emergency situation , so you can wait to get your insurance ready and get started.
Hope I have answered your question. If you have any further questions I will be happy to help.
