Catrin - Just off the top of my head it seems that you report an awful lot of endos. In my decades of riding and observing both my own and others' crashes, most are to the side. I think I've gone over the bars one time in decades of riding, but countless times every other direction. My husband has gone over twice but one time was his own stupid fault (trying to do a nose wheelie without thinking it through

).
Are you focusing on getting your butt back? If so, focus on getting it back
more.
