Another name for tetanus is “lockjaw”. It often causes a person's neck and jaw muscles to lock, making it hard to open the mouth or swallow. CDC recommends vaccines for infants, children, teens, and adults to prevent tetanus. The most common initial sign is spasms of the muscles of the jaw, or “lockjaw”.

Where do you feel lockjaw?

A common first sign of tetanus is muscular stiffness in the jaw (lockjaw). Other symptoms include stiffness of the neck, trouble swallowing, painful muscle stiffness all over the body, spasms, sweating, and fever.

What is the reason of jaw lock?

If you are experiencing issues such as jaw clicking and locking, you may have temporomandibular joint dysfunction (usually referred to as TMJ/TMD). TMJ/TMD occurs when the temporomandibular joint becomes damaged or inflamed due to an injury, inflammatory disorders, and other such issues.
