you'll live.....that green puss is likely nuttin'....but goin' to a doctor is never a bad idea, but he'll porlly just tell ya itz healin' itself.....2 yrs ago or so i did a major wipe out on a long board and got some serious road rash on my knees and elbows, my right knee had a gash that was like 4 centimeters deep and 2 inches wide and about 3 inches long, so i dumped some rubbin' alcohol on it and covered it with band-aids, and it kinda got all green pussy like too, so i went to the doctor, and he just said it was healin' itself......but, like i said, goin' to a doctor is never a bad idea....you could always just call 'em and ask about it
