Could My Hot, Prickly Episodes, Rapid Heart Rate, And Anxiety Be Related To Menopause Or Sjögren S Disease?

Hello, I m 54 and I may be going thru menopause, I have sjogrens disease, newly diagnosed. My question is , I m having these episodes of my face getting hot and prickly and really, hot, I ll get a fast heart rate and I ll feel it pounding. I feel like I m having these surges of adrenaline, I hyperventilate. It feels like a horrible anxiety surge, it keeps coming back intermittently. These episodes come when I m anxious, I have high anxiety, and it will feel hard to take a deep breathe. They also come when I m trying to sleep at night. I may have sleep apnea and I can really feel my heart go crazy and I ll wake up breathing fast. I m afraid , because I feel I can t calm myself down and It s like my body is just doing its own thing, what could this be?
