Please Help?

Im 17 and about 4 years ago me and a friend were playing around on his block where he lives. We decided we wood do something crazy and ride shopping carts, we found some blocks away, down the street. so were riding the shopping carts in the street for sometime and one time we went on them cars came in our direction. we both tried to turn to opposite sidewalks to avoid being run over, he rolled onto the curb without a probelm. I on the other hand didnt and the shopping cart flipped on its side with me in it. I blacked out for a second and when i woke up i got up and felt lightheaded. The shopping cart had stabbed me in the arm with i guess the part of the metal bars that stick out. it wasnt beeling but the cuts were deep. i had no idea of why i wasnt bleeding because it was literally really deep and i could see the inner layers of skin and stuff. well it bruised up and healed i guess. i didnt go to the doctor and i developed a rash? it like a bunch of pimples and skin darker than mine.

See the doctor immediately. Your long term health is important. Don't risk long term infection. Your life is valuable, honor yourself.
Reply:u need to get to dr. the shopping cart could have had something on it, thus injecting it into u when it stabbed u.
