Swelling of the parotid glands is the most common symptom of mumps. The parotid glands are a pair of glands responsible for producing saliva. They're located in either side of your face, just below your ears.

Both glands are usually affected by the swelling, although only one gland can be affected. The swelling can cause pain, tenderness anddifficulty with swallowing.
