Hi, my husband has severe graves disease and has had his thyroid taken out because of cancer. He took a radiation pill which made his graves disease much worse. He took about 15 weeks of 500 mg. intervaneous I.V. for his graves too. Now he is like a wet noodle. No energy, no stamina, no strength, etc. They have him on 150 mg. of meds for his now gone thyroid. What can we do?
