Many people search for boil or cyst when they notice a painful lump, swelling, or bump under the skin.
At first glance, boils and cysts can look similar, which often leads to confusion.
Some people want to know whether the lump is infected, while others search for treatment options, pictures, and home remedies.
Questions such as boil vs cyst pictures, how to treat a boil or cyst, and boil vs cyst vs abscess are among the most common searches.

Quick Answer
A boil is a painful skin infection caused by bacteria, usually involving a hair follicle. It often fills with pus and becomes red, swollen, and tender.
A cyst is a closed sac under the skin filled with fluid, keratin, oil, or other material. Most cysts are not infections and grow slowly.
