I just found your post. This is the first time I have ever posted/replied to anything on this cite. I just have to know what you have found out. I have searched and read hundreds of blogs/postings for months about migraines and other problems people have reported and have never found anyone with symptoms so similar to my own.
For the past two years, I have been having episodes where I will begin to feel intense pressure in my head, not pain, just pressure. I get very light headed and feel as if my thinking is very slow. Those around me notice immediately that I cannot process information at my normal rate. I too have tingling in my face and other parts of my body. My hands usually get very cold, often to the point that my finger tips turn purple. My brain seems to slow down to the point that within minutes I am unable to speak or move. I can still hear what is going on around me, but am unable to respond. Sometimes I do not even blink for minutes. I become nauseated and very cold. Once I am able to move and become able to verbally respond, I am very cold and need a blanket. I remain mentally slow and sometimes confused for up to an hour.
After CTs, EEGs, MRIs and other tests, my neurologist ruled out seizures and said I have basilar migraines. I do not know if I am satisfied with that diagnosis. Obviously not or I would not still be looking. Please let me know if you have found out anything.
