It started less than a year ago with cluster headaches. The headaches then changed to burst of pain that would blur my vision and cause such pain that I would be kind of out it for a few moments. They never lasted very long. Since the last burst which, thank God, has been over a month ago, my head is numb on the right side. I am having vertigo and numbness in my head, right side and back. At times I lose my thoughts, confusion sets in or forget in the middle of something what I was going to say or do. I even went to step out my door to my house which has a couple of steps down and its like my brain forgot to tell my feet to step down. I almost fell flat on my face.
