Up to 20 percent of patients with mumps will experience no symptoms, according to the Centers for Disease Control and Prevention (CDC).

In patients who experience symptoms, mumps may start with one or more of the following:

• General sick feeling (malaise)
• Fever of up to 103 degrees Fahrenheit (39.4 degrees Celsius)
• Chills
• Sore throat
• Swelling of the temples or jaw (temporomandibular area)
• Weakness or fatigue
• Headache
• Face pain
• Loss of appetite
• Muscle aches

The most highly recognized symptom of mumps is swelling and pain in the parotid glands (glands located below and in front of the ears that produce saliva in the mouth). Fever and malaise usually precede this swelling. The glands normally become increasingly swollen and painful over a period of one to three days. The pain is usually worsened by chewing, swallowing, talking or drinking acidic juices (e.g., orange juice).

Both the left and right glands may be affected, with one side swelling before the other, or only one side swelling. In rare cases, swelling may occur under the tongue, under the jaw, or down to the front of the chest.

Other symptoms that may be present in men include:

• Testicle pain
• Testicle lump
• Scrotal swelling
