Hello everyone, this is my first post. Last night, I was at a bonfire with a bunch of my friends. Some of my friends were messing around with a knife and were heating it over the fire. It turned red with heat. My friend picked it up and turned without realizing that my bare arm was directly behind him. It burned down a few lairs of skin and is basically just white. The area surrounding was fairly swollen but it never hurt THAT bad. Today, my arm is really sore, probably from chopping wood, but i'm paranoid that it might be tetanus. Is this possible? There was no blood, but the knife was around the dirt. I have had a tetanus shot within the last 2 years. I put bactine and neosporin on the wound within 2 hours and it has been covered for the past 24 hours. Do I have anything to be worried about?
