So today at work about 11:30am a huge breaker box fell on my foot and landed on my big toe right between the toenail and the toe. It immed. turned black and purple and began to blood clot. I walked around on it for awhile (it bled some) and it was hurting pretty bad. Well after lunch I was limping around and limped onto a freaking rusty roofing nail! It went straight through my shoe and into my heel, began to bleed like crazy. After that I decided it best to call it a day and go home. Its been about 3-4 yrs since my last tetnus shot, should I go get another one? They are good for 10yrs I believe, what do you think ?
