What did the doctor test? Was he having hypo symptoms before starting meds? What were his symptoms?
Panic attacks and tiredness/fatigue are symptoms of hypo, but the doctor really should have tested FT3 and FT4, along with TSH, before starting meds. TSH of 7 is high, but TSH is a pituitary hormone and subject to any number of influences.
The throat itching is most likely psychological or has some other cause. Tirosint is hypoallergenic and only contains T4, so individual doses don't really "kick in", rather levels build slowly over time in the blood.
I'd have FT3 and FT4 tested to make sure that TSH reading wasn't an aberration.
Diarrhea is a symptom of hyper (overmedication).
My advice still remains to have FT3 and FT4 tested, with a repeat of TSH, as soon as possible. Should your doctor balk at those tests, you can order them from an online lab without a doctor's order. Self ordered labs are also self pay. Whoever orders them, be sure they order FREE T3 and FREE T4. FREE must be specified, or you will get total T3 and total T4, which are not as useful.
Thank you, I will call the doctor Monday.
I also want to mention my son has Raynauds, he said his symptoms change. Is this related to his stomach issues
I don't know that much about Raynaud's, except for its symptoms, but I think it usually affects the fingers and toes and not the stomach.
