Mumps usually has significant pain, mostly in the zygomatic arch or in the heel of the ear. The first aspect is that the painful salivary gland secretion increases when food is eaten, especially acidic food, due to obstruction of the salivary gland ducts. The second aspect is that the subcutaneous tissue covering the surface of the parotid gland may develop localized edema, significant skin swelling and pain, or mild tenderness, sensory allergy, and surface burning in some patients. In many patients with mumps, the submandibular glands may also be involved and may become enlarged and painful. In addition, the lymph nodes in the neck are usually enlarged and painful bilaterally in patients with mumps.
