Thyroid issues — maybe –???
I didn’t relate to your story until you mentioned your husband bumping the bed and how being startled like that provoked more symptoms.
I had an experience like that — husband comes and bumped the bed. I was sound asleep and it so startled me — my heart was pounding… I ended up with a major panic attack. I couldn’t figure out where this had come from. To make a long story short — I found out I had thyroid disease. The thyroid is involved in almost every function of your body.
Have you had your thyroid tested — ?? — dunno… just an idea.
I hope you figure something out and that you feel better soon.
