I'm a hypothyroid (for at least 15 years) 35 year old male (6 ft, 73 kg) trying to get myself well on NDT now. My vitamin D, B12 are both in great ranges for good thyroid absorption. My iron panel perhaps needs work - see previous posts (even though ferritin is fine according to many). My brain MRI and heart echocardiagram are all clear. My 4 point saliva cortisol looks fine as well. But this post is not about blood tests or other results. I want to see if anyone has these specific symptoms that started for me about 3 years ago.
These particular set of symptoms are in addition to your usual hypothyroid symptoms, such as feeling cold, low energy, short/medium/long term memory recall, and so on. No, these extra symptoms come on suddenly.
The heart/chest starts feeling weird in a kind of a pain (angina?) that can migrate around the chest and to the back. The face muscles around the mouth and nose area feel numb so that facial expressions feel unnatural (but totally doable - I'm not actually losing control of any muscles). I also feel a bit shaky and somewhat anxious. I start to have even more dreadful thoughts. A little lightheaded too. My irritability increases even more than usual and ability to "care" about things decreases lower than the normal already "low" threshold. Most other symptoms such as coldness increases too. So this is like a temporary extreme hypothyroidism...
The acute phase of this goes for a day or two. Then there is usually a recovery after another day or two after that and I feel fine, which is my usual set of symptoms that seems nothing compared to when I have this cyclical thing come on.
I have noticed that these attacks increase in frequency as I increase my thyroid past certain point. That point is a lot lower than my optimal upper quartile T3 and TSH < 1. This occurred for me when I was on Levo (T4), then when I was on pure T3, and now when I'm on NDT working my way up the dose.
My theory revolves around this being a kind of an anxiety attack, caused by me not absorbing the thyroid properly and this is the thyroid pooling effect. Getting my iron panel optimal is my only chance here. Perhaps looking into oestrogen dominance as another source of not absorbing thyroid, but it doesn't seem a popular theory on these forums.
Basically I'm worried about increasing my NDT higher to get better thyroid panel at the expense of not being functional! Should I even drop my NDT lower for a while? Who knows, but at effectively 2 month adjustment periods between doses it's not something I want to take lightly. I am working towards my optimal dose - currently slowly raising the dose, not lowering it. Hence, need advice...
Has anyone experienced this? Has anyone got it diagnosed? Has anyone treated it successfully? Very interested in people's thoughts...
