Mark,

thank you for your answer, it made me think a lot. Today is the first day I am feeling a little better, the worst thing is the hyperacusis. After the last three concussions it always went away within a few weeks.

So you mean not hitting my head, but my rising blood pressure after the bump can cause all these symptoms? But shouldn't the symptoms go away when the blood pressure is down again and not stay for days?
Normally my blood pressure is very low, sometimes to low, so I cannot take medicine to make it go down.

Canadoc,

thanks for your words, it's so good to hear that I am not the only one that feels this way.
How do you deal with the days that you spend recovering? Do you have a job? I have a good job, but sometimes I am afraid I will lose it, due to so many days off, because I'm not feeling good.
