Thanks Mark for sharing knowledge, putting things in perspective and taking time to answer me. And I know you are right. It seems extremely unlikely that a hit like that would normally constitute a concussion.

But the thing is, I got immediate symptoms, which I normally dont get when bumping my head, and I havent been as bad in 3½ years as I am now - I can almost only stay home and rest. It has all the hallmarks of a concussion!

In the weeks up to the bump with my daughter, I worked far too much and slept to little, and I was generally overdoing it with social activities, and I hadn't completely recovered from a bump with a lamp a month ago. I knew it was too much, but I thought I could catch it later, which I normally can. But because of this perhaps my brain was in a weakened state, and therefore my brains tolerance/threshold for concussion was lowered. I think that makes sense.

I will go for a walk, and try to be positive, but thanks for listening.
