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.
Hi, Cluster headaches are awful...possibly worst headaches known to man.  The other headaches you are describing are most likely a form of dysautonomia as well and could be a slightly atypical hemicrania continuum since the numbness overhead seems constant.  There are many things you can do for clusters and headaches in that family which are referred to as trigeminal autonomic cephalic (TAC).  You need to find a headache specialist or a neurologist very well versed and who really makes it a passion to treat and manage headaches.  Do not settle for someone who really doesn't wish to really approach these to find out what's at the root of your headaches if possible and then, offer you legit treatments that have a chance of working.  Hope I have answered your query. Let me know if I can assist you further.
