What does lockjaw mean?
Lockjaw, also known as trismus, is a medical condition characterized by sudden and severe spasm of the jaw muscles. This condition often leads to difficulty in speaking or swallowing and is commonly associated with tetanus infection. Tetanus, a bacterial infection, causes muscle stiffness and spasms, which can result in lockjaw. The condition can be life-threatening if not treated promptly. Understanding lockjaw and its connection to tetanus is crucial for timely medical intervention. The term 'lockjaw' is sometimes used interchangeably with tetanus, although technically it refers specifically to the symptom of jaw muscle spasm. Lockjaw can be caused by various factors, including tetanus infection, and requires immediate medical attention.
