I am hypothyroid - I recently had a procedure involving a large dose of iodine based contrast. Then 3 days later due to extreme pain, I had an abdominal CTscan with iodine contrast. Approx. 1 week later, I began suffering from severe episodes of anxiety, hot flushes and high spikes in blood pressure, which landed me in the ER three times in 2 weeks. Cardiac tests were OK but now my TSH level is running low. I do not have Graves Disease. Has anyone heard of iodine contrast causing thyroid storms?
