I had thyroid ablation in 2001 and yes you have to watch for signs of thyroid storm after this procedure . It rarely occurs, but can happen.
What T # is 24? There's TSH, Free T3 and Free T4... It definitely sounds like you are hyper, but it would really be helpful if you could post all of your latest thyroid test results, with the reference ranges listed on your lab report, since these ranges vary from lab to lab, so must come from your own report.
I don't know why doctor said that destroying your thyroid would cause thyroid storm....... thyroid storm is a life threatening condition that occurs during untreated hyperthyroidism. Destroying the thyroid would cause you to go hypo, which is what will ultimately happen anyway.
