Hi codee,
Thank you for reaching out to us - we're glad you're here!
I'm sorry you are having a rough time getting to the bottom of your symptoms. While your symptoms sound like they could be a migraine attack without the headache phase, silent migraine, I can't speculate on exactly what's going on. I can share information on this type of migraine with you that can be shared with your doctor; https://migraine.com/migraine-types/.
Keeping a detailed migraine diary is a good way to identify our triggers and any patterns our attacks may have. When you get a chance, take a look at this information on how to keep a migraine diary; https://migraine.com/blog/keeping-migraine-diary-basics/.
You may want to investigate seeing a "true" migraine/headache expert. These doctors are board certified in headache medicine which is different than being certified in neurology. These articles explain more; http://migraine.com/blog/how-are-migraine-specialists-different/ and

Keep us posted on how you are feeling,
Nancy
