What Could Cause Recurring Episodes Of Lip Tingling, Fuzzy Head, Vision Changes, Trembling, And Jaw Clenching?

Hi, I have been having symptoms for a few months now. I get tingling and numbness in my lips and fuzzy feeling in my head. I have seen my family doctor and a neurologist. We have done EKG s, bloodwork, and an MRI. The symptoms have been getting worse. I now get double, tunnel, or just blurred vision. It gets down right scary to drive. Only happens for a few seconds at a time. It almost becomes a feeling of passing out but I don t lose consciousness. I get trembling in my arms and legs on the worst of these spells . I ve even bit my lips and tongue for no reason other than my jaw clenches suddenly. I feel like I have a very hard time focusing on things when this happens. Resting can help but it doesn t make it go away. These spells could last just a few minutes or up to three days with these symptoms. When it goes to three days, that s when all of the symptoms come to play. Short spells are mainly lip tingling and fuzzy head feelings for a few minutes. We have adjusted all my medications to see if that would help as I am on multiple things for chronic migraines. I want to seek a second opinion but seeing as I don t know what an issue could be and test have been inconclusive, I don t know how to approach a doctor. Could you help guide me?
