A whitehead from a sty indicates the presence of pus, which forms when the body's immune response fights an infection, typically caused by bacteria in a blocked gland near the eyelid. This blockage leads to inflammation and swelling, resulting in the characteristic bump. While sties are generally harmless, they can be painful and may require treatment if they persist or worsen. It’s advisable to avoid squeezing or popping a sty to prevent further infection.
