Dear Jacustomer ,
I am sorry to know about your symptoms .
I will recommend that your doctor does anti ro and anti la antibody test as underlying undiagnosed autoimmune
disease ,sjogren disease can present with similar eye dryness and pain as you mentioned . Rose bengal stain can also be done for the same underlying cause .
Migraines is diagnosis of exclusion , we need to do other tests before reaching to the diagnosis of migraines . Sinus exam also needs to be done as that may present with similar pressure and headaches .
Ear exam (epley maneuver ) should be done to rule out benign positional vertigo as a cause of your dizziness .
I will also recommend a cervical exam , cervical xray as you said that your symptoms got exacerbated with exercise ,so we need to rule out cervical pathology (cervical spondylosis ) .Eye fatigue
seems less likely or else you would have complained of double vision .
After ruling these all out ,then migraine should be considered as that also may present similarly .
Feel free to ask further questions if any.
