Are these things usual?? When I'm falling asleep and only when falling asleep, I often get woken up startled with a strange but intense feeling of numb waves starting in my head and going through my chest. It often startles me to open my eyes and I'll check my heart rate and breathing and usually its within range. Is it normal to feel so tired that I'm afraid im going to pass out, get dizzy, or fall asleep where I sit or stand? My feet or one foot tingles whenever it wants to. After I eat the strange feelings become worse. My memory seems to be very bad and sometimes throughout the day I'll even become uncoordinated and often act a little confused. This all passes but has been going in for close to a year now. Is this normal for hoshimotos sufferers? Also, I can no longer tolerate the heat of the sun or getting too hot. And when I tried to walk up a hill in the sun yesterday my heart felt like it was beating out of my chest and I had to actually focus very hard on not passing out. Is this NORMAL???? I've posted my recent labs many times, testosterone low, all other TSH, T3 and T4 normal. Low ACTH but doctor not interested in finding out why. Testosterone way low hey doctor not worried. I used to work out daily and could do spin class and run miles. How do I safely get back to working out? I don't want to be fearful to exercise for a whole year!!! That won't help any of this. Anyone else know if these things are normal????
