Wikipedia lists "panic attacks" under possible symptoms of hypothyroidism. I don't have them, but I do know another hypothyroid person who does. She has also had a lot of depression and mood instability.
There was that medical study that concluded that T3 supplementation in addition to standard T4 treatment helped improve mood and mental functioning in hypothyroid patients. Later studies tried to repeat the findings and found no improvement. Hmm...it's definitely worth a try though. Just make sure you're getting regular TSH tests to make sure you aren't suffering anxiety from too much thyroid hormone.
Anxiety is a major symptom of hypo and hyper thyroidism. Both diseases chemically unblance the bosy and other hormones and alter the stress levels for us.
Mediction like anti anxiety meds are sometimes needed to mask the receptors that are triggering the panic - but the end result and to end that war is to properly get balance with the hormones.
Usually - unfortunately it is one of the last symptoms to go away - but when it does your life will change dramatically in a good way.
Stabilizing the thyroid hormones is key and until you get that under control you may need assistance with medication.
As for your question about T3. This is a a binded protein and testing plain T3 is not going to give you the right lab levels.
Your doctor - if you are pooling T3 should be testing your FREE T3 and FREE T4. If your
FT4 is high and FT3 is low that is where the blocking/binding or pooling would be taking place.
i have the same problem ever since my TSH and thyroid antibodies have been elevated i've had severe paranoia, depression along with severe bouts of lethargy, nausea burning on the right side of my body feeling faint and blurred vision and almost complete inability to drive at night because the lights make me dizzy and nauseous along with it
I had panic attacks about 20 years ago when I worked with all women who smoked some of them chained smoked and I put it down to secondary smoke my thyroid was perfect at the time but also my job was so stressful our boss used to come in every morning and say there were too many women working and as such that was unproductive hours (worked for a construction company where 99% were men) and that one of us would have to go and he would stand there looking at us as if he was trying to decide which one of us to sack. In the end I saved him the trouble and resigned and then my panic attacks stopped and haven't had them since.
I am having terrible panic attacks, but mine seem to be mostly at night.
I am on armour and it not adjusted properly yet. I can't figure out if the T3 is causing the panic attacks. I read too much will do that.
