I am extremely clumsy and have fallen on my butt many times just doing silly things (for example I was trying to squish paper in a trash bag that happened to be on a concrete floor so I got the great idea of jumping back and landing on the bag with my butt and squishing it...lol well the bag flew out from under me and I landed on the floor..hehe)
But anyway I am pretty sure that things like that have something to do with it as well .
Thanks for all of the feedback everyone!! I really apprieciate it. I guess I was wondering if anyone else has it and has pinpointed what it is coming from, because like I said it gets worse after a hard ride...thanks again!!!
