Signs and symptoms of tetanus may appear anytime from a few days to several weeks after tetanus bacteria enter your body through a wound. The average incubation period is seven to eight days.

Common signs and symptoms of tetanus, in order of appearance, are:

  • Spasms and stiffness in your jaw muscles
  • Stiffness of your neck muscles
  • Difficulty swallowing
  • Stiffness of your abdominal muscles
  • Painful body spasms lasting for several minutes, typically triggered by minor occurrences, such as a draft, loud noise, physical touch or light

Other signs and symptoms may include:

  • Fever
  • Sweating
  • Elevated blood pressure
  • Rapid heart rate

When to see a doctor

See your doctor to obtain a tetanus booster shot if you have a deep or dirty wound and you haven't had a booster shot within the past five years or aren't sure of when your last booster was. Or see your doctor about a tetanus booster for any wound — especially if it may have been contaminated with dirt, animal feces or manure — if you haven't had a booster shot within the past 10 years or aren't sure of when you were last vaccinated.
