Has any of you ever had a thyroid storm? If so, what was it like. I think I have had two, the first time, the er told me I was having a panic attach and sent me home, and I told them it was not, I had panic attacks before, but never like this. I happened again two days ago, but not nearly as severe. I stayed calm, even though it was hard to breathe. Last time and this time, I was out of it for a few days after. It started with a hard hard heart pounding, then a heaviness in my ches, very hard to take a breatht. Then my hands and feet started tingling intensely, them ,my lips, it would travel up my arms and legs. I would get lathargic, and it was hard to think straight, and it was hard to for my mouth to form words to speak. My eyes,,,,,,,,,,my eyes felt peeled back, and it was like I was in a weird zone. My mom told me that it may be a thyroid storm. That day I did see a doctor, she was pressing on my thyroid, while she had me try to swallow water. I am not sure what I am anymore, Hypo or not. I do know that I have several goiters from an ultrasound last week. I just want to know if anyone else has had this experience.
