You may have broken the spur at the tip of your elbow. I did this and it hurt like hell! It won’t impede your training (other than the pain), there is nothing the doctors can do aside from pain meds and in my case the way it healed was actualy better, more rounded, till the next lacrosse season when I got wacked in the same elbow again and broke it again! Stupid attackmen don’t know how to throw a good poke check!
