wenting biking along a trail by flint ridge park in newark, oh. was goin a bit too fast into a turn, tighter turn than i thought.......with mud, dirt and algae all over the pavement (river can flood this part when high). well started to loose it than almost gained control when my rear wheel locked up and slid out......causing me to slam my head into the ground

. plus road rash and few other cuts.
anyhow, my left eye is swelled and getting a black eye. is anything that I can do to make this heal faster? EDIT: what about scaring?
