Thank you both for replying. I have done a little reseach online and it looks like this all could be part and parcel of concussion. Sometimes the symptoms only manifest themselves way after the injury.
My dizziness is transient so I can cope with it. Sorry to hear you both are still having problems. Its the nausea thats the worse but than goodness since my post I havent really got that back. I do find though I am off my food a bit and not enjoying my favourite tea etc so much!
The tinnitus is the worse thing at present its driving me nuts!
Thanks again and good wishes to you both.
