I had radioactive treament due to
Graves Disease, and six months later my thyroid was declared dead. I was put on levothyroxin, synthroid and now levoxyl, but 3 months later I still feel awful. My symptoms are high blood pressure, constant trembling, feeling like I have the flu, dizziness, insomnia. My last blood test showed a TSH at 3.21, Free T4 at 1.0 and Free T3 at 3.1.
