Hi! I got my labs back last week. T3 norm, T4 norm, TSH low .045. So, I'm on 50 mg PTU, switched from Tapazole because of elevated liver enzymes. Anyhow, I've been on PTU for 7 months. Now, endo wants RAI. My only symptom now is heart palpitations, my heart rate is usually 70ish. Not hot, no trouble sleeping, no diarrhea, a little jittery and I have lost weight, but I've been trying and am training for a 5K. Anyhow my appointment is today, what should I ask or suggest? I don't want RAI, but I've had hyperthyroidism for 20 years. What should I do? Thanks!

Kate
