I can't offer you any help at the moment, but I can tell you you're not alone. I'm on my 9th month of a continuous migraine. I'm a 31 year old male, have only had migraines once every year or so, and then 9 months ago I wake up to flashing lights for a few seconds, realize then from that point on I'm having a 24/7 visual migraine aura, I see billions of spots and speckles all of the time. My vision is 20/20, I just can't see 1/3 of everything. In combination with that, I have difficulty finding words, writing, typing, I forget things easily, walk to the mailbox 3x a day sometimes, sleep horribly, and my newest symptom is being drunk with vetrtigo, and I've never even drank alcohol a day in my life. When I walk sometimes I require a person on each side of me because the room shifts balance and I fall and stumble, people laugh at me sometimes as if I'm drunk. I've had all the tests, spinal tap, ct x10, mri x5, EEG, bloodwork, seen an ENT, neurologist, MS specialist, seizure specialist, neuroopthomologist, you name it. Some docs say it's "Psychosematic" That I'm creating it for attention, some say it's related to my white matter damage to my brain, which they won't say where THAT is coming from and progressing... but you're not alone. I'm starting on Topamax, but to be honest, I just watched a documentary called Under Our Skin... and I think any person with chronic health issues should consider that possible an offending substance may be attacking multiple organs. "Under Our Skin" is the name, it's about Lymes disease and how our medical community misdiagnosis' it. I pray you find health, I am God gives peace and sustains our health even though it's hard, and if we find healing it's a blessing through Him. My next path is to try the Lyme protocol they recommend, because I'm learning most doctors have been of zero help my entire life.
Hope all goes well!
