Most thyroid nodules do not cause symptoms and are so small that you cannot feel them. They often are found during a physical exam or when another test, such as a CT scan or ultrasound, is done for a different reason.
If your thyroid nodule is big, you may be able to feel it or you may notice that your neck is swollen. In rare cases, you may also:
- Feel pain in your throat or feel like your throat is full.
- Have a hard time swallowing.
- Have a hard time breathing.
- Feel nervous, have a fast heartbeat, sweat a lot, lose weight, or have other symptoms of hyperthyroidism (too much thyroid hormone).
- Feel tired or depressed, have memory problems, be constipated, have dry skin, feel cold, or have other symptoms of hypothyroidism (too little thyroid hormone).
