stress/anxiety when I don't feel the stress/anxiety?

I am a walking talking billboard of weird symptoms. I've gone to plenty of doctors over the past 6 years and have always had a clean bill of health, but I feel terrible lol.

It usually starts out with stabbing headaches that move around my head and face. It includes pressure in my head and face as well. The headaches last every day for months. I go to a headache specialist who recently prescribed me a new medication to help the headaches. Took the medicine and the headaches have subsided a lot. However, shortly after starting the medicine, everything went crazy.

The issue is, I have had these headaches in the past, and when the headaches subside, then I get a lot of neuro symptoms that eventually go away after a few more months. But the neuro symptoms can be disabling.

So, what has happened most recently (I believe a lot of it was a side effect to the medication) I started having these dizzy spells. After the dizzy spells, my face starts sweating and tingling. My jaw and tounge start to get a teeth chattering tremor. My tongue feels weird and then I get uncontrollable nausea and vomiting. I have prescription zolfran for the nausea and dizziness but it doesn't help at all. Then I start to feel twitching and muscle cramps throughout my limbs. The tips of my fingers feel like they are losing sensation. They then start to feel hot and stiff. All of this happens within an hour like a wave and all while I've been feeling cool as a cucumber. I do get anxiety from time to time, but short lived and mild. After a couple hours, all the symptoms subside and go back to normal. But it usually happens a few times per day.

I've been to multiple neurologists and the Mayo clinic. I've had all the tests done multiple times. The only things I have ever been told is benign fasciculation syndrome and stress. I know it's nothing to worry about because it will go in remission for like a year, then come back. Big diseases don't do that. But can you have all the severe symptoms I have (which I only mentioned a few) from stress and anxiety you can't even feel?
