My daughter in law was in a snowmobile crash and got a concussion. After suffering thru that trauma, she was in a store and bent over to look at something and when she stood up she jammed her head into her neck, hitting a shelf. Since that occurred, she has had tingling in her face and arms, clenching her teeth involuntarily, head bobbing involuntarily and eye closing involuntarily. She has foot drop and pain in her leg. She has had multiple MRI's, blood tests and Dr. visits, to which they all say they can't find anything. She has been tired and sick feeling and trying to live as though nothing is wrong, but I am worried that this could become a way of life for her, when it isn't necessary with the right diagnosis. She's been tested for Lyme's disease (her job is with the govt going to farms to manage their manure waste) and multiple other things, such as MS, thyroid disorder, etc. Does anyone know of anything that sounds like this??? We are at wit's end, trying to diagnose this by ourselves.
