A throat nodule is a growth or lump that occurs in the thyroid gland in the front of the neck, according to WebMD. Throat nodules are usually not cancerous, and many do not need treatment. Thyroid nodules are common with aging, though the cause is not clear.
Large nodules can produce the following symptoms: a pain in the throat or a feeling that the throat is full, difficulty with swallowing or breathing, feeling nervous, rapid heartbeat, sweating, or weight loss, states WebMD. The last four symptoms listed are indicative of hyperthyroidism, in which the thyroid overproduces thyroid hormones. When there is too much thyroid hormone, the gland becomes suppressed and does not work as much as usual.
