Thanks again everyone for your prayers, it really helped Well, Noah is going to be okay!!! We're waiting on the results of the blood test, but his heart looks normal on the ultrasound - so they think it is an overactive thyroid. I guess it is a very treatable disease. My question for all of you now is...there is an option of radioactive iodine ($1000!!!!) or a pill for the rest of his life. Has any of you done either if these and can give me some insight into how it all works - pros and cons?? He needs to get treated asap because his heart rate is over 300bpm. My poor baby!!! Thanks again
