I've got a wound through a dirty/rusty metal last year. after the healing, it turned black and keloid also appeared. I didn't able to see a doctor 'cause I thought it was just normal since I'm just 16 y/o. I didn't felt any symptoms at the first month, but after some few months, I've experienced the lockjaw and some others. But now, I didn't feel any symptoms anymore. I'm just kinda worried if I do have a tetanus. THANKS.
Tetanus occurs fairly soon after the wound is created. It has to do with the bacteria Clostridium Tetani creating a toxin that causes the symptoms of Tetany which is persistent muscle contractions all over and not necessarily in the jaw. IF you were to have gotten Tetanus, it would have occurred much sooner then now.
