Eventually, an area of pus appears on top of the boil, explains WebMD. A boil on the eyelid is known as a sty. Boils also come in clusters. When they do, the cluster is called a carbuncle. The infection that gives rise to a boil can worsen if it is not treated. In that case, the skin around the boil becomes inflamed, painful and swollen, and more boils erupt around the first one. The person might also become feverish, suffer from chills and develop swollen lymph nodes. These symptoms are reasons to seek medical help.
A patient should also see a doctor if red streaks appear around the boil and the pain becomes intolerable, notes WebMD. A doctor should also be sought if the boil does not drain. People with compromised immune systems or those who suffer from diabetes, a heart murmur or are generally in bad health should also seek medical help if they develop a boil.Learn more about Skin Conditions
