I had much more anxiety when I was Hyperthyroid. I also get flushed across my neck and chest even when not stressed. It usually starts right in the area of the thyroid. It happened 5 times last week. Good the last few of days. Sometimes I feel like I should be on anxiety meds, but I don't want to depend on them.
I havent had panic attacks as such, but I definitely feel much more anxiety than before. I also get flushed across my neck and upper chest area even when I'm not particularly stressed which makes it very embarrassing when I talk to people!
People name it panic or they call it anxiety, it's the same thing though when our bodies react to either a situation and we feel unable to deal with it or unconciously feel agitated for no reason.
Many people who are hyper also have this happen. It seems to be a biochemical set up rather than a true disorder. Unfortunately in the really old days people were locked up and given electric shock treatment in a hope to cure them....if only they did a thyroid function test.
Now to answer your question; Yes I had and still occasionally do have panic/anxiety attacks. I was undiagnosed hypo then swung into hyper and then found after 15 years I had/have Hashimoto's disease. I was put on 5 times the normal dose of Efexxor and had a terrible time. Thank fully I understand now, how the endocrine system works and refuse to take any anti-anxiety/depressants to treat my episodes.
i didnt notice any panic behaviours prior to hypothyroid problems; heaps of anxiety but not really panic. any panicking became (more) marked at the time i became hypo, and improved as my thyroid levels normalised.
good luck
Mine started after my diagnosis. Technically I have not been diagnosed, but it's really what I have. I have hashimoto's toxicosis, and have spent the last 7 months swinging back and forth between hypo and hyper. The heart racing and constant fluctuations have caused me to have constant panic attacks. I always feel like I have too much adrenaline floating around. The constant panic attacks due to my body malfunctioning has led to me not wanting to spend a lot of time in public places due to fear of having these attacks. In my mind, I don't even think these should be called panic attacks as they are medically induced. I am on a beta blocker which has helped more than anything. I hope you find some peace and rest. Panic is horrible!
