There is definitely evidence that previous concussions make you more susceptible in the future, even if you feel l ike you made a complete recovery. Also, from my own experience, I am certain that I have been more susceptible to concussions than other people ever since my first one at the age of 9.

However I have yet to meet a doctor who is aware of this evidence, or who will accept it - which to be honest hasn't really mattered since it doesn't make any difference to their 'treatment'.

Do be careful though since I see you had your injury at work. I found that whilst doctors had no interest in my concussion history, my work was very interested since I foolishly/concussedly told my manager I had had concussions before, and this was used to justify not giving me sick pay, since they argued that although my concussion happened at work they shouldn't have to pay because I had had concussions before.

So I would advise not telling anyone this if you think it might cause you a similar problem.

With regard to the reading, I really missed reading for a while as it would bring back all my symptoms. I found that I could listen to audiobooks during that time, you may want to try it. It seemed to go into my brain with fewer processing difficulties.

And I see you mentioned difficulties mixing coffee. I found that caffeine made my symptoms worse, and have completely cut out both caffeine and alcohol.

Best wishes
