You need antibiotics to prevent an infection. I don't mean to sound alarmist, but I read about a teenager who nearly died of MRSA after stepping on a toothpick. You might have donenerve damage, but you have to give it time to heal first to see how it does.
You also need to be current on a tetnus shot. Have you had one in the last several years?
Forgot mention I stepped on a toothpick.
