I took the skin off my baby toe in a bike accident. It became immediately swollen and now constantly weeps yellow/ green puss, please help!?

I feel sorry for . What happened happened , have him see u pcp for evaluation and treatment.
See a podiatrist. It sounds like you are in need of an oral antibiotic. A wound culture might be a smart idea as well.
Abrasion. I would use triple antibiotic ointment 2-3 times a day and keep a bandaid on it to protect it from further trauma (ie shoes, etc). If spreading redness, pain or other symptoms occur, you may need oral antibiotics.
