Hi. I was absolutely horrified when I read this thread - and it has actually prompted me to start posting again.

Please, please stop whatever you are doing and shut yourself in a dark room for 3 weeks!

Coming up 10 years ago my head was knocked twice or rather I knocked my head twice. - the knocks were 6 weeks apart.

I thought that I had got over the first one straight away, but approx 2-3 days afterward I had severe headaches etc.

The second knock gave me instant headaches, memory loss and all the other symptoms to go with it. Because I couldn't get the right diagnosis etc I kept trying to work full time. I believe this been the cause of my non recovery. (Plus my age did not help being over 40)

Like Mark I have got my survival/ self protection tricks - which I think are developed instinctively for self preservation.

All the best, I will no doubt have more to say later.
