Last Nov my t3 & t4 were elevated & my tsh was a bit low so I took methimazole 5mg for a month. I checked my ft4 & tsh after both came normal. Am I ok?

Maybe. I wouldn't self manage, even if I have been through this before, you need to be followed by a doctor, preferably an endocrinologist, thyroid gland is a complex one, and there are more tests needed for evaluation, needs an expert, hope you find one, good luck.
