Hi welcome to the forum and the wonderful world of trying to get treatment for concussion in the UK.

From my limited experience since my own injury 9 months ago it seems that you have some of the most common symptoms. These are not surprising considering the fall you had and the previous one 6 years ago. It is quite common for successive concussions to compound the damage each time causing a longer recovery time.

I too suffer from getting my words out and comprising written text. Although sometimes when I think I am slurring or pausing between words people have commented that what I am saying is coming out fine. Myself and other posters have mentioned that it is not uncommon to feel that you are a third person watching yourself talk.

As you say the feeling you get is like trying to talk or do something when you have had a drink and your mind is trying to function but the words or limbs don't function properly - and to make matters worse you get all the symptoms of a giant hangover - headaches, sensitivity to light and noise, dizziness and nausea.

Hang on in there and follow the advice on this forum to rest and maintain a clean diet
