A stye, also known as a hordeolum, is a small abscess (painful collection of pus) on the eyelid. It appears as a painful lump on the outside or inside of the eyelid.
Symptoms of a stye
A stye (also called a hordeolum) causes a painful swelling on the outside or inside of your eyelid. There are two types of stye, internal and external.
Causes of a stye
A stye (hordeolum) is usually caused by an infection with staphylococcus bacteria. These bacteria often live on the skin without causing any harm.
Treating a stye
A stye (hordeolum) often gets better without any treatment, particularly after it bursts and has released pus. Most styes should go away on their own within one to three weeks. Do not try to burst the stye yourself.
Complications of a stye
While styes (hordeolums) normally get better without treatment, they may cause some complications. However, these are rarely serious.
