I had my 3rd concussion on june 28th. the feeling of being lightheaded has not gotten any better and i've been out of work since. has anyone experience feeling lightheaded worse than any other symptom. i'm starting to get really depressed about it cos it hasn't gotten any better. i have a neurologist appt in 2 wks. thank god. will they be able to do anything? any advice would be helpful. i'm getting scared at this point.
