Monday I was just heading out and over -reacted to a car coming out of a driveway,jammed on my front brakes and my rear wheel flew up and threw me over the bars.I put my hands down to break fall,and twisted my wrist and banged my knee a bit.So I cont'd to ride to work(my knee hurt more at the time)got to work and my wrist /lower arm got worse,long story short radial head fracture at the elbow
