--you've just been through a number of procedures, and are on various medications, and I'm not sure that a lot of what you are reporting, although it should be checked out, is not temporary, and reactive.

Thyroid nodules are very common, and Mel, they may be completely asymptomatic, though ultrasounds to find them are often done on people with suspicion of low thyroid function. (My wife is one--she has a small nodule but documented evidence of low thyroid function via anti-thyroxin antibodies, and takes a small dosage of Synthroid.) I'm assuming, Roxie, that part of the reason for the thyroid ultrasound was all the other issues, especially autoimmune ones (the most common cause of low thyroid function is autoimmunity)--did they do the standard TSH, free T3, T4 levels?
