Some people do not have any symptoms. They might find out that they have a thyroid nodule incidentally when their doctor feels it during a routine check-up. Or a doctor might find nodules on an imaging test that was done for another condition.
Eg: sonography/CT/MRI of neck
Some people have symptoms. For example, they might feel or see a lump in their neck. Or they have symptoms from having too much thyroid hormone, such as:
- Feeling worried, upset, or having trouble sleeping
- Feeling weak or tired
- Losing weight without trying
- Having a fast heartbeat
- Having frequent bowel movements
