CA-Lynn has left no stone unturned so I don't think I could do better.abbytabby said:
I am wondering though what your mom's labs look like. There is a slight possibility that she could be over-medicated or receiving or taking in too much iodine from vitamin sources or seafood or some supplement she is taking? This would cause an allergic reaction i.e. skin rash.
Has she had her TSH, FREE T3 and FREE T4 run recently? If so, results and ranges would be appreciated. How much Levothyroxine is your mom taking every day?
