If there are sliding bumps on both sides of the neck, it is recommended to go to the hospital for a local ultrasound to clarify whether it is a lymph node or a thyroid swelling. If it is a lymph node, a routine blood test is recommended to see if there is an increase or decrease in white blood cells to rule out a bacterial or viral infection and to guide the clinical use of medication. If a thyroid mass is suspected, commonly thyroid nodules, thyroid adenoma or even thyroid cancer, it is recommended that a blood test be performed to see if there is an increase or decrease in T3 or T4. If thyroid cancer is highly suspected, a local biopsy is necessary to confirm the diagnosis.
