Parotitis is an inflammation of the parotid glands, which are the largest salivary glands located near the jaw. This condition can be caused by viral infections, such as the mumps virus, bacterial infections, or blockages due to salivary stones. Symptoms often include swelling in the jaw area, pain, and difficulty swallowing. Treatment for parotitis depends on the underlying cause. Viral parotitis typically resolves on its own, while bacterial parotitis may require antibiotics. Staying hydrated and applying warm compresses can help alleviate discomfort. In some cases, addressing blockages may involve medical procedures.
