I do not have cold extremities, but I do experience something resembling your throat and chest problem. I do have hypothyroidism and altho they did not test me for Hashimotos, I had an ultra sound on my thyroid because the Dr felt a lump. The ultra sound was normal, tho.
This comes and goes: Sometimes when I am eating, it feels as if my throat and whatever is next -- (esophagus?) are all tight, clogged, as if there is a lump. And it will hurt really bad as the food goes down. Then I will experience a LOT of pain in my (upper) chest and it will take a few minutes to subside.
This scares me only because I read a lady's account of a heart attack: She experienced pain as her food went down and the pain went down into her chest. She thought it was merely the attempt to swallow whatever she was eating. Turns out it was a heart attack.
This does NOT happen every time I eat. Also -- at times I cannot swallow my vites to save my life. I used to swallow literally a handful of vitamins at once, throat, neck, etc
opened wide up. Now, sometimes a little 500 mg of C sticks in my throat and often, I have to cough it up and try again.
But again, this comes and goes. If it is not my thryroid, I dont' know what it is. But your difficulty sounds similar, altho I didn't note you mentioning this happening while eating. That is the only time it happens to me, and again, it does not happen every time.
When it does happen, the chest pain is remarkable, altho I cannot say severe.
I wonder what it is?
