well, since your levels fluctuated so quickly, i'd wait for the two weeks. i have silent thyroiditis, which is similar to what you have...except i think the hyper and hypo phases last longer for silent thyroiditis. i was hyper for months before being diagnosed, and then i went hypo. i've been on synthroid since july/august 2008. i am currently being tapered off of synthroid.
what are your free t3/free t4? i would make your determination more off of these values than tsh.
if in two weeks your frees are still lowering, then the doc will put you on meds. if they're rising, then your thyroid is healing and you'll continue to be monitored for several more months to make sure you return to normal.
even if you go on meds today, it'll likely take at least 1-2-3 months to feel somewhat normal. all the while you'll be wondering if you even needed the meds in the first place. eventually the docs will try to taper you off meds, and you'll continue with the med cycle again.
hang in there for two more weeks, and if it doesn't get better, go on the meds to allow your thyroid to heal. if your tsh is lower, continue to get monitored frequently to make sure your levels are returning to normal.
this is just my opinion.
me...silent thryoiditis
tsh .004 march 2008 with free t3 thyrotoxicosis, free t3 5.2 and then
tsh 56, free t4 .53, free t3 1.6 in july 2008 then put on
112 synthroid from july 2008
tsh of .099 in april 2009 with normal free t3/free t4
and tapered to 88 synthroid...and still feeling good...we'll find out more in july...
I did get a Free T4 test done. It was low .605 which is not extreme. The doctor's feeling is that if I take synthroid now I will never know if my Thyroid would have gone back to normal on it's own. Lot's of people with subacute thyroiditis eventually go back to normal without medication. I just worry about damage I am doing to my body by letting such a high TSH level go unmedicated for 2 weeks.
With those results and feeling like you do, I sure wouldn't wait for two more weeks. I would go back as soon as possible and get new tests done. Make sure the tests include free T3 and free T4 along with thyroid antibodies, and TSH. Maybe these tests will show what is going on and get you started on meds. quicker.
