I get a buzzing feeling in my head often, since I was a child. I rmember the first time it happened I though I was feeling radio signals going through my head. Over time I have been diagnosed with ADHD and feel that my mental functioning and memory had detiriorated. I am 26 now and feel like I can't keep it together inside my noggin most of the time, and I still get the buzzing feeling deep within my brain or over the surface. I don't know what to do.
