Update...and still having the night issue

Hey everyone:)
So good news..I got the results to my biopsy today and the nodules on my thyroid are not cancerous! Very good news, yes. :)
BUT..i'm still having this night issue with the fast heart/bad breathing sensation. I've been taking a whole beta blocker everyday for well over a week, as well as an acid reducer and i'm still getting these night time issues. They started off only once or twice a week, and now it's basically every single night. And i'm always waking around the same time with this. The endocrinologist said she does not think my thyroid has anything to do with it because my blood tests has shown my thyroid levels being normal and not enough to cause symptoms. I asked if maybe one of the larger nodules are hitting my wind pipe or affecting my breathing somehow while sleeping and causing this, and she said very likely not and she thinks something else is going on.
She made me an appointment on the 26th with a pulmonary doctor and to probably get a sleep study done.
All I know is my breathing has been worse recently, not just in the middle of the night, all the time..almost like a slight burning in my nose/throat when I breathe, then feeling like i'm breathing too fast. The fast heartbeat I get in the night is different from my daytime fast heartbeat that I get from anxiety. My normal fast heartbeat that I get I can feel my heart pounding in my chest, this nighttime fast heartbeat I can't feel in my chest...i'll wake up and I initially don't feel anything, I just feel off..then i'll feel my pulse and it's between 80-90 bpm. But I can't actually feel it pounding in my chest..which for some reason almost scares me more. I will prop my pillow back up and almost sit up to fall back to sleep and it seems to slow it down initially, but when I wake up again it's doing the same thing.
Sorry this is so long..but also just want to add that it seems like once daylight comes, if I fall back to sleep..It doesn't happen! Like when I put the baby down for her morning nap, if I lay down and fall asleep, it doesn't happen then! I'm soo confused what this could be!? Even after taking a beta blocker,an acid reducer, and a xanax..I still wake with this. SO CONFUSED.

Hi GMoon,

What you are going through sounds a heck of a lot like everything my wife has been going through. Check the NEW thyroid level standards that came out this year. Most doctors dont know about and they are using the old standards.

My wifes levels were fine by old standards but we found out that ANY change in thyroid function can cause symptoms just like what you are going through. Also, have you had a tilt table test yet? After many visits to a lot of doctors my wife had one and she was DX with POTS, (Posterier Orthostatic Tacicardia Syndrom) (excuse my spelling). This is not a FAKE problem and it can answer many questions. Once my wife got that DX she got on the way to being able to live a better life now.

Good Luck and Never Give up.

Awesome News on your biopsy!! And good job on going for a sleep study, they are a piece of cake if you have any questions about it just ask, I've had it done.

Sorry you are still suffering though, How about watching a mindfulness video before going to bed?
