I've been suffering from a multitude of symptoms, the worse being extreme lightheadedness and fatigue and most recently swollen and painful lymph nodes in the back of my neck- right under the hair line. About a month or so ago they found a large complex cyst on my thyroid and did a biopsy, which came back benign. My thyroid blood tests came back within the normal range. The Endocrinologist told me that my symptoms aren't related to my thyroid because the blood tests are within normal range, but I would think that a large cyst would affect the way the thyroid is functioning. Do you think I should get a second opinion?
A large cyst is not likely to affect thyroid function in most cases -- if the labs are normal, then the thyroid hormone levels are likely not the culprit. In some cases the large cysts/goiter/nodule can press on the carotid artery or jugular vein and may cause some light-headed feelings -- this is NOT common, so would consider a general evaluation for the other symptoms as it may not be related to thyroid.
