Tetanus is a bacterial infection that produces painful, rigid muscle contractions, especially in the jaw – which is why it is often referred to as lockjaw. Tetanus enters the body through wounds, commonly, puncture wounds. Symptoms of tetanus include headaches, cramping or spasming of the jaw muscles which then spreads to other muscles such as those in the neck, arms, legs and stomach. Treatment is through hospitalization where antibiotics and antitoxins are administered, and wound drainage is performed. Traditional Chinese Medicine is also a treatment option. Tetanus is rare due to vaccination.
