Thank you for your response. This is my first time to get a terrible sick and pain in neck. Which doctor should I go for ENT evaluation? Should I go back to my endocrinologist? Please reply me so I know what to do.. I appreciate your advice.
This is a very common finding, no specific followup is required for a 2 mm colloid cyst. If the thyroid ultrasound is this normal, the neck pain is not likely related. Consider ENT evaluation.
