This is a small nodule that is borderline for needing FNA biopsy. Risk of cancer for nodules in general is 5-10%. A nodule like this would not likely cause any symptoms.
yes - Graves can cause menstrual irregularities - call your doctor to report the dizzy/light-headed symptoms to confirm why that is occurring.
in most cases there would be no benefit from treatment with these levels but rechecking TSH along with TPO antibody may be reasonable
This is not likely all thyroid related - would make sure TSH is normal and consider a rheumatology evaluation.
A low TSH usually means hyperthyroidism -- 15% of hyper patients do gain weight. Depending on the situation, you may need treatment -- especially if TSH <0.1 and T4/T3 are elevated or you have hyper symptoms (you listed mixed symptoms). Consider an endocrine consult or second opinion so you have a better understanding of what is going on with the low TSH...
The high TSH means HYPOthyroidism. We rarely use combination PTU and thyroxine. At this point looks like staying off the PTU and treating with eltroxin (w/ or w/o cytomel) is most appropriate to bring TSH back to normal. See an endocrinologist if there is still trouble normalizing the numbers.
No - this is normal. slightly low T3 levels cannot be used to diagnose hypothyroidism -- we rely on TSH for this (and T4).
Our practice is limited to thyroid and parathyroid, which can cause bone loss but the best next step for you probably is a general endocrinologist or rheumatologist for the osteoporosis workup.
Sounds like hypothyroidism due to hashimoto's - key with the ultrasound will be to confirm those "holes" are areas of inflammation -- so see a thyroid specializing endocrinologist.
It depends - most of the time it is chronic hypothyroidism and most likely the initial dose was simply too high.
