Sounds like thyroiditis to me...I had T3 toxicosis...hives...tachycardia. They caught mine at a very early stage of Graves Disease. Burned my thyroid out and am now doing very well, hypothyroidism is much easier to treat with thyroid replacement therapy. Sure hope that is all it is with your husband.
I will keep him in my thoughts and prayers.
