I started on
Armour thyroid 30mg 3 days ago and I woke up today with headache, dizziness, and unbalanced. My story started 1 month ago when my doctor started me on synthroid 50mcg. I developed left facial heaviness, dizziness, and unbalanced after only taking synthroid for 10 days. My Endo doctor told me to stop taking synthroid. I stop taking synthroid for 2 weeks, and the dizziness, left facial heaviness, and headache never completely resolved.
