Ear lumps can be single, multiple, pain-free or sore, states Healthgrades. They may quickly increase in size or stay the same. Local infections often cause the growth of ear lumps in the form of boils or abscesses. Various kinds of infections cause the enlargement of the lymph nodes close to the ears. These swollen glands may feel like small lumps on the skin. The common traumatic causes of ear lumps include insect bites and serious injuries that lead to the buildup of blood in the tissues.
