hand tremors and eye floaters

[Guest guest]

My daughter is 16 and is having some health issues and I am wondering if they

might be iodine/thyroid related. She has terrible hand tremors that have been

going on for a few years, but recently they have gotten a lot worse... She also

has floaters in her eyes (these have been checked out by an eye specialist and

we were told they were fine and of course they don't know what the cause is),

and constipation...even on 500mg of magnesium a day. She has always had a hard

to get a long with personality too. When she was an infant she was breastfed for

3 months, but then bottle fed. SHe had terrible colic and the doctor put her on

soybean formula (wondering if this caused a thyroid problem). Ever since then

she has had stomach aches, etc. Right now she is taking Vit D3, magnesium,

probitoics, and iodine 12.5 mg. SHe has been on these for about 1 month. Any

ideas/suggestions?
