Will a chalazion get better after it starts discharging pus?
In general, whether a chalazion improves after pus drainage depends on the severity of the condition, treatment methods, and individual circumstances. The specific analysis is as follows:

If the amount of pus discharged from the chalazion is small and there is no obvious redness, swelling, or pain, gently cleaning the area with a sterile cotton swab and keeping it clean and dry usually allows the condition to gradually improve. In individuals with strong immune systems, inflammation will slowly subside as pus drains, and the lump will gradually shrink and eventually disappear without requiring extensive medical intervention.
However, if improper management leads to residual pus or secondary bacterial infection, noticeable eyelid swelling, worsening pain, or even fever may occur, making spontaneous recovery unlikely. In such cases, inflammation may spread and lead to an eyelid abscess, requiring prompt medical attention for incision and drainage. Delayed treatment may result in scarring that affects the appearance of the eye.
To prevent complications, avoid rubbing your eyes with hands and maintain good eye hygiene. Eat a light diet, reduce intake of spicy and greasy foods, and consume more fresh fruits and vegetables. Ensure adequate sleep and avoid staying up late, which can weaken eye resistance. If a hard lump appears on the eyelid, early warm compresses may help promote resolution. Seek medical advice promptly if abnormalities occur, and never attempt to squeeze the lump yourself.
