Nancy, I don't know if I figured it out - it was more like survival! At first I thought resting was lying on the couch and reading a book in front of the television screen!. Of course, I couldn't read or watch as couldn't concentrate or keep my eyes open. I was also told to "wait", "just rest while you are waiting to get better" That was told to me by a private neurologist - who unfortunately died in my first 6 months. Well it has been a mighty long wait!!! Especially when you are not patient! I think that your son has to avoid ever hitting his head again, like don't play soccer, rugby etc it is not worth the risk. Never believe what specialists from any insurance company tells you - they have been my biggest problem and have their own agenda. My favourite saying is peace calm relax....................... - then if you are lucky you won't get a headache!!
