I was diagnosed with hyperthyroid/Graves disease in July 2007. When this first occurred, my symptoms were pain in back, neck, head and left arm, fast heart beat, body tremors, dizziness, weakness, heat intolerance and increased saliva. I was so debilitated during these episodes that I had to lie down and could barely speak. I had to be in direct air conditioning or air and my daughter would have to use a massager on my back. The pain would subside after about 15 minutes. My primary care physician first sent me for a stress test which was not normal. She then noticed that my neck was swollen and performed tests for my thyroid. At the time my levels were as follows: T3 768, T4 4.5 and TSH 0.01. When I was going to take the iodine test, I had another episode in the doctor's office. I was sent to the emergency room where I had an abnormal EKG. My cardiologist performed a catheterization and thought there were blockages. After a CT angiogram, there were no blockages. However, they said that I had arterial spasms. I have since been prescribed Tapazole (first 30 mg daily now 20 mg daily), Imdur, Lipitor, niacin and a baby aspirin daily. I am 44 yrs old. Has anyone had spasm in association with hyperthyroid. When one of these episodes is about to begin, I can feel it coming. If I take an Imdur, the pain subsides in my neck and back. My levels currently are T3 190.1, T4 0.8, and TSH 0.02.
