Do tetanus cause swelling in the arm?

Tetanus is a serious bacterial infection that affects the nervous system. The bacteria that causes tetanus, Clostridium tetani, enters the body through a wound and produces toxins that affect the nerves and muscles. Tetanus can cause a number of symptoms, including:

- Stiffness of the jaw muscles (lockjaw)

- Difficulty swallowing

- Stiffness of the neck and back muscles

- Painful muscle spasms

- Sweating

- Fever

- Headache

In severe cases, tetanus can cause death.

Swelling in the arm is not a common symptom of tetanus. However, it is possible for swelling to occur in the arm if the infection spreads to the muscles in the arm. If you have swelling in the arm along with any of the other symptoms of tetanus, you should see a doctor immediately.
