T3 under or over

Hi all

still unwell. Hospital lost my blood test from last Saturday with endo.

I am responding however to post about circadian t3.

First I had always took t3 all in one go following Dr Lowe procedure.

Tired individual dosing but felt rotten.

Have gone back to one daily dose.

My question is If I was on175mg of t4. Now on 75t4 and 20t3 does this mean I am under medicated at 135mg. Been unwell all year.

however I to have high heart rate over 100bpm but low resting at 35bpm. Went to optician and they said that my evens are too dry in the lower half of the eye . Have to go back in 2 weeks. She says that at night my eyelids are not closing overmmy eyes.

She is right last couple of nights I am not sleeping. Feel terrible pressur behind eyes and eyelids not closing. I have gone from sleeping like a log like in a coma. But still feeling tried inam. To not sleeping. Having really bad nightmares bad headaches.

really irritable. Still have problems walking high temps and very low temps. Burning mouth and sorry burning vagina and bladder problems.

am I over or under.

still trying to get bloods back.

but I am worried about my eyes.

Kjc1Tisdell, Hospital needs to find your results or repeat the tests as this is the only way of determining whether your current dose is adequate.

Hashimoto's and hypothyroidism can cause dry eyes and you may need to use preservative free eye drops or ointment to keep them adequately hydrated.

Thanks for your reply optician gave me two items that my gp needs to give me free on persciption . But wouldnt need if meds where right explained everything to optician. Very helpful but where concerned about eye health.

Administration at GPS trying to track records. This is annoying as I don't have to ask for copies of things anymore as I have signed up for online access to my medical records. And can make appointments etc online. Which is brilliant.

Might be a good idea to ask for your B12 levels to be tested? Some of your symptoms could be due to low B12, dry eyes, burning mouth etc... It is not unusual for low B12 to accompany thyroid problems, and for symptoms to be similar. Best wishes MariLiz
