So ignorant about lab results, just want help.

I can't believe I found this board; it is SO wonderful. I could spend hours here just learning from everyone. Anyway, I have been having some strange things start to happen to me and I'm trying to narrow down what it all could be related to. I'm 38, not overweight, have hyperT, and am on Synthroid 137.5. This has gradually been increased over the years. For the past few months I have been getting tingling and numbness in my hands, not really bad, but enough to notice, along with a slight shakiness/tremor in my hands as well as internally (if that makes sense?). I've been lightheaded and dizzy on numerous occasions and have developed pain in my wrists, ankles and hands, and sometimes my joints pop. I also have random muscle pains all over as well as muscle twitching. And In just the past week, my eyesight has become a little blurry when I blink. I'm a nervous wreck too, so I know that's not helping the matter. AFter all bloodwork came back normal, GP sent me to a neuro-MRI of brain and spine came back normal, except for a small pleural effusion. (I am going for diagnostics tests for this next week.) But I was wondering if anyone could interpret my thyroid results and see if there is anything amiss?

TSH 2.19 (0.450-4.500)
T4 8.1 (4.5-12.0)
T3 Uptake 38 (24-39) It says this is a percentage?
Free Thyroxine Index 3.1 (1.2-4.9)

Other things I'm worried about are the other typical autoimmunes like MS, Lupus and Lyme, but I wonder if there could be something here to explain why I feel so bad all the time.

Any advice would be greatly appreciated!!

Your thyroid levels are ok, but a tiny increase in dose may help you feel a little better. Your additional symptoms, especially with a pleural effusion, could be suggestive of lupus, which causes many symptoms, some you mentioned, and extreme fatigue. I would be sure your additional tests include tests for lupus.

Re: So ignorant about lab results, just want help.

I'm not so sure your thyroid levels are okay.
TSH for someone being treated for hypothyroidism - or for any healthy person without thyroid disease, for the matter - would be expected to be in the 1.0 or slightly lower area of the range. Your T4 is low for a woman; a healthy woman would have total T4 in the upper to slightly above-range area of its range.

Furthermore, that set of thyroid tests is outdated and inaccurate. It would be better to check the level of free T4, not total. If you happen to use estrogen-based birth control, the total T4 level is completely inaccurate; in that case, it's vital to test free T4.

I can't say whether your symptoms would have roots only in inoptimal thyroid levels, but also can't say whether your thyroid levels are fine based on the panel of tests you've had. Try to get your doctor to test your free T4 (and free T3, if you can convince him to do it) instead of total T4 and thyroxine index.
