Two days ago I had my first Ji-Geiko in Bogu. I received some hits in Men and they were so painful to me (they almost just throw away all my enthusiasm to Kendo away). I had a little pain to the end of the day and today still feel something (not painful) on the top of my head. Is my head so weak or most people you fight don't hit so hard as my partner in ji-geiko? Have you ever have problem like that?
