@kai123 Thanks for your encouraging response!
I'm glad for you that new little bumps in the head don't flare up your symptoms anymore - that's awesome.
Since I started this thread, my reaction to tiny hit was gradually improved too!
Nonetheless, I am also more cautious about bumping my head again as a tall guy, still bearing in mind the first strong bump.
So it's kind of a combination of the two - I protect my head more than in the past and at the same time when I happen to hit the head I try not to freak out as much.
So far so good!
All best,
