The top of the reference is outdated, it was set by the AACE to be 4.3 .
It is curable indeed but with lots of patience, this test (TSH) is the test that shows the thyroid gland function, if it is high then you have hypOthyroidism , and if it is low then you have hypERthyroidism, in other words , it goes counter intuitive.
The next step is to determine the cause for your TSH being high, you should ask your doctor to run antiTPOab and TGab, those are thyroid antibodies, that can cause hashimoto's disease, an autoimmune thyroiditis, it has no cure, but treating the underlying hypo is suffice .
The treatment for your Hypothyroiditis is to take Levothyroxine pill , to bring your TSH down, your Doctor is going to prescribe for you a low dose of Levo and to increase it gradually until you reach stable levels and feel no more symptoms, by the way, are you aware of any ?
Your TSH is super high and I assume you feel crappy .
Regarding the Levo brand names that are available, if you live in the US then there are Levoxyl , Synthroid and Tirosint, if you live in Europe , then they use Euthyrox and L-thyroxine , insist on brand name rather than generic, since this will keep your weekly dose consistent .
Good luck and let us know if you have more questions ,
