Hi! For a lil back ground, I am just shy of being 27 yrs old, I am in good health, not over weight, I'm fairly active, I do suffer from migraines (diagnosed 12 years ago) and I was in a bad car accident 9 years ago and had a severe concussion from it. (the left side of my head was swollen out 3" off normal size) No MRI or any test were done. 5 years ago the left side of my head and body went numb. Dr at ER said it was stress, no test were run. Now for the past 2 years I have had what I would call "bolts of lightening" go through my head. They last about 10 seconds to a minute or so and then they are gone! These have been occurring more and more often as time passes. 3 weeks ago I had the worst pain I have ever experienced. It was to the base of my head and it lasted for about 2 minutes, I beleive I lost consciousness b/c for severl seconds my husband said he could not get me to respond, then the pain died down to a minor headache that lasted for about an hour. Since then I have had 3 instances that were the same, just not as severe as the first time (pain wise) and 6 times were to the right side of the base of my head. Again, the pain still was not as bad as the 1st time, but bad enough that I would rather have a full blown migraine then this type of pain. My husband has noticed as well as I, that my memory is slipping. I who had the memory of an elephant have trouble remembering the simplest things. I am very scared! Can you give me some insight as to what this may be?
