Hello. I Was Bike Riding A Few Days Ago And

Hello. I was bike riding a few days ago and rode a bit too fast. My feet went under the metal pedals which results in several scrapings leading up to my calf and my ankle area. It really hurts to walk in that area. I cannot feel my foot. I've done research but no luck. Is this urgent? Can i fix it at home or should i go to hospital?
