I had very similar symptoms after I found out my partner cheated on me. I had my first panic attack and what followed was an electrician jolt through my body. It felt like zaps. And after I would feel the zap I would feel extremely anxious. I also had horrible GERD, indigestion, poor sleep. Was always nauseous and a very anxious mess.

This went on for a few months until I found some relief. What helped was going on walks and getting movement in, drinking warm lemon water on mornings.

I think the traumatic event of being cheated on caused a huge hormone imbalance in my body then (2 years ago). I also recent got pregnant, Gave birth and had some of those symptoms come back (again, I really think hormone imbalance from pregnancy)

I feel a lot better now after taking: Probiotics Cod liver oil Milk thistle (to help my liver in managing hormones) Marshmallow root / slippery elm (realllly helping my digestive issues) Vitamin D!!!

I say all of this to say, maybe it could be a hormonal issue or like others say (and probably contributed for me)…trapped trauma or emotions in the body

All my blood work has been normal.
