Emersonjanebrown: Thank you so much for all the information you have provided for me (even in perfect Norwegian). I'm sorry to hear what happened to you, but so happy you have responded positively on the treatment. I will definitely try this!

The strange thing about my symptoms is that they are mainly physical (not cognitive) and usually go away after a few weeks (but not this time). I wrote that I had some problems with talking fast - I think this was because of my pain. When I'm not in pain I have no problems with concentration - I can work extremely much and long days without noticing anything wrong. My doctor therefore thought that there might be my neck that cause my problems now (he does not deny that I've had several concussions in the past). He said it is likely that everytime I (slightly) "bump" my head, some signals remember how it was the last time, and "create" the headache and other concussion symptoms, even though my head probably is not "concussed". What do you other guys think of this? How much force is required to cause a concussion?
