Re: TSH range source, and a few questions
Sounds like a thyroid issue....and sounds like you are one of too many people not being diagnosed properly.
Knowledgeable doctors are aware of the fact that TSH higher than 2 is suspect for hypothyroidism.
And, if a knowledgeable doctor saw your TSH and heard about your symptoms, he/she would then run additional thyroid tests - the actual thyroid hormone levels (TSH is a pituitary hormone).
He/she would need to run the FreeT4 test (T4, free, direct) as well as the FreeT3 test (Tri-iodothyronine, free, serum).
I suspect your results would show one or both levels to be lower than mid-range, if not towards the bottom of the range or even below range.
Now, based upon your earlier symptoms, they sound hyperthyroid (overactive thyroid)....some of your current symptoms sound hypothyroid.
You might want to research Hashimoto's disease which is an autoimmune thyroid disease - the most common cause of hypothyroidism.
Hashimoto's autoimmune attack on the thyroid results in eventual destruction of the thyroid. As the thyroid destructs, it can often "throw off" thyroid hormones which can result in hyperthyroid symptoms (and temporary hyperthyroid levels).
Often, there is a hyperthyroid phase before the ultimate hypothyroidism sets in (but there is always the chance of those hyper moments as the thyroid destructs)
You just might want to read "What Your Doctor May Not Tell You About Hypothyroidism" by endo Dr. Ken Blanchard. He explains much of what I just shared with you as well as a great deal about hypothyroidism in general and its proper treatment.
