I has a head injury almost 20 yrs ago. For the past few months I have been feeling very odd, almost like I am hallow inside, light headed, the muscles in my left hand get very tense. These feelings seem to kick in more when I am driving on the freeway. I have been to the ER a few times and they say there is nothing wrong because I start to feel better in a few hours. They say it's neuro. I did have a cat scan down while at the ER and they did say I had slight brain damaged due to my injury quite some time ago. I do have an appointment for a 2nd neuro. but it is in 3 weeks. This is happening more rapidly lately, the first nero said it could be seiazures so they put me a meds, but this does not seem to be helping. I am afraid something else is wrong and don't know where else to go. I can not see me waiting another 3 weeks just to be looked at and then tell me to go get test done. Just was wondering if there is another approach or what could be going on.
