Tetanus is a serious but rare condition caused by bacteria getting into a wound. The symptoms of tetanus usually develop 4 to 21 days after infection, with an average of 10 days. The most common type of tetanus is called generalized tetanus, which begins gradually and then progressively worsens over two weeks. The symptoms of tetanus include:

• Stiff jaw: This is also called lockjaw and is one of the most common signs of tetanus.

• Stiff abdominal and back muscles: These muscles may also be affected.

• Contraction of the facial muscles: This can cause a facial expression known as risus sardonicus, which is characterized by a raised eyebrow and a smile.

• Fast pulse: This is also known as tachycardia.

• Fever and sweating: These symptoms may occur due to the bodys immune response to the infection.

• Painful muscle spasms: These spasms can occur anywhere in the body, but are especially common near the wound area. They can be severe and may be triggered by minor events that stimulate the senses.

• Trouble swallowing: This can occur due to muscle stiffness in the neck and throat.

• Breathing problems: These can occur due to muscle rigidity in the neck and abdomen.

• Pneumonia: This can occur if things like saliva or vomit accidentally go into the lungs.

• High blood pressure or abnormal heart rhythms: These can occur due to the bodys immune response to the infection.

• Pulmonary embolism: This is a blockage of the main artery of the lung or one of its branches by a blood clot that has traveled from elsewhere in the body through the bloodstream.

Tetanus is a life-threatening disease, and if you have signs or symptoms of tetanus, you should seek emergency care.
