Have you ever heard of ocular migraines, or migraines with aura?? I get those. I get all kinds of visual effects, the longest it has lasted is about 4/5 hours, then cleared. You can have silent migraines with aura, sounds nuts, huh??? I will hurt in my temple, then it travels to the corner of my forehead, then to my eyeball, sometimes to my nasal passage, my jaw and teeth. I have had it in the back of my neck, to travel the back of my head, left to right....odd. I was taking Depakote 1,000 mg., but stopped to see if it helped my tremors ( I have essential tremor). It did not. I now take Topamax. I hated taking those "horse pills" anyway.
I hope he gets better!

And......I do not wish TOOTH PICK MIGRAINES on a dog!!
