Causes of neck swelling include skin conditions such as acne, boils, cysts and skin infections; serious medical conditions such as throat cancer, anaphylaxis and angioedema; neck injury; and neck surgery, according to Healthgrades. Conditions such as goiter, mononucleosis and mumps may also cause neck swelling. Ear pain, on the other hand, may result from jaw arthritis, tooth infection, acute or chronic ear infection, and sinus infection, notes MedlinePlus. Sore throat and ear wax accumulation can also cause ear pain.
