Did you have free T4 done? It could be seconary hypo?
My TSH and free T4 are both low & was diagnosed with secondary hypothyroidism.
Secondary is caused by failure of the pituitary & could be pituitary tumor or cyst.

Scriv, are you on any thyroid meds at this time? If you're taking hormones then your TSH means little, you want to go by your FTs (not your Total T3, but your Free T3)
Also, are you eating low carb? Very low carb can cause both T3 and TSH to be lowered - it's your body's way of slowing metabolims when it percieves that you're dieting. Restricting carbs low enough to cause ketosis can hinder your body's ability to convert T4 to T3, simply increasing carbs if you're doing LC can help aleviate this.
FWIW, when my FT4 was really low I had constant headaches and I'd get this eye twitch that just wouldn't stop; it was very scary and quite distracting.
A foolish consistency is the hobgoblin of little minds.
I am on 125 mcg thyroxine and the T3 is the free T3 reading. For some reason they did not do a T4 test, but my doctor has asked for a full thyroid profile at the beginning of Feb.
No, I know about the low carb problem. I am easily hypoglaecaemic so have to watch an adequate and frequent carb ontake anyway.
I also have a constant headache and annoying twitch at the moment as well.
I must admit I am thinking of a pituitary tumour..I have been in contact with my optician today and he is to check the optic nerve on Monday.
I'm sorry, I don't know what tmj is, angel....
Scriv, I've got the same problem. Low tsh & low T3. This past week, and even now, I've got mild headaches, and pressure in my eyes. They aren't dry, everything just aches. If you figure out what is going on, please post it. How does one know if their pituitary gland is in rebellion? What are other symptoms? Will it show on regular blood work?
Renee, I'm so pleased to find someone else with the same problem.. I think my doc is trying very hard not to worry me. She can't retest until Feb - she said the thyroid could be affected by stress or a virus, so wanted to give it time to settle down (or otherwise) before another reading, which she hopes would clarify what is going on. She is also testing for antibodies - I think the TSH receptors on the thyroid can sometimes be blocked by these.
But I still worry about this eye business...a few weeks ago the eyelid drooped significantly, but went back.
