Trimus
The redness and swelling of the parotid gland may also result in difficulty unlocking the jaw, known as trimus. This symptom may be as severe as to cause problems in day-to-day activities such as eating, speaking, and keeping an adequate oral hygiene. In some cases, it may compromise swallowing, and it becomes a distressing problem for patients, especially younger ones.
Trismus is a prevalent symptom in many different diseases, and your doctor will need to perform a few diagnostic tests to rule out joint problems, periodontal infections, and tetanus infection. You might experience trismus after certain oral surgery procedures, especially after molar extractions, and it is caused by inflammation of the nearby tissues. Thus, if you or your child have this symptom, talk to your doctor as soon as possible and follow his recommendations.
