Silent Thyroiditis?

So, here is the deal. I just got a call from my regular doctor this morning saying that my blood test work which got done last week showed an overactive thyroid. Again. This was just a routine check up so I'm seeing my endo doc on Thursday.
Last time I got my tests done were in April when they showed an slight overactive thyroid. I was prescribed beta blockers. Before that, almost a year ago, I went through a phase of an overactive thyroid that lasted about a 3 months. After this period, my values were normal. My doctor thought it was a case of silent thyroiditis. During this time, an ultrasound showed enlarged lymph nodes around my thyroid and a thyroid nodule but my doctor didn't think a biopsy was needed.  Anyone out there with this condition? The sites I've visited so far don't really mention anything about it being a recurrent condition. Could it be something else?

If this is chronic thyroiditis the hyper- phase can come and go more then once.
if your nodule is larger then 1 cm and COLD the biopsy is necessary.

When you see your Endo...ask for a TSI (Graves antibody test) to be done.
Graves can do this recurrent thing...mine was like this for years.
