Re: Can a 9mm cystic nodule cause pain?
The nodules are probably not causing the pain. The most common condition that causes thyroid nodules is autoimmune thyroiditis, called Hashimoto's. This condition is caused by antibodies that are produced againstnyour own thyroid cells, which results in inflammation. It is the inflammation that causes the pain, and sometimes enlargement of gland (GOITER). Part of your workup should be anti-thyroid antibodies, as well as hormone levels for thyroid function (TSH, free T4 and T3). Frequently an antiinflammatory like OTC Naproxen will help some with the discomfort. You can also try ice packs on your neck for relief. Eventually, if you have these antibodies, the gland will gradually stop functioning and you will need thyroid medication. Sometimes early on the thyroid is overactive and needs suppressed, hence why the hormone levels are important. You may have already had these tests, if so, this will just help explain a bit.
