so i grabbed a piece of wood today to do build a countertop and there was a staple sticking out of the end about an inch and i grabbed the wood and the entire staple went into my hand. I pulled it out and it bled for awhile. now hours later my palm where the staple went in is throbbing and red, I think i had my tetanus about 5 years ago, should i be worried?
Welcome to Chat Doctor, A small piece of wood might have pierced and may be left in that place, so it has to be carefully removed you might need a booster dose of tetanus toxic.  Clean the wound take-out any remaining nice left over in the hand regular Chat Doctor. Hope this explains with regards
