I got cut with a rusty nail and it's swollen and busied up around the cut. should i be worried?

Rusty Nail: If it has been more than 10 years since your last tetanus booster, contact your doctor to bring your immunizations up to date. A booster vaccination is also recommended if you sustain a deep, contaminated wound and more than five years have passed since the last dose, since protective antibody levels may fall after five years in some people.
