Cellulitis from a stye: what to know

A stye is usually a tender, localized bump at the eyelid margin. Cellulitis is a deeper skin infection that may make the eyelid or nearby facial skin feel hot, sore, tight, and increasingly swollen. Redness may extend beyond the original bump. A stye itself does not prove that cellulitis is present; an examination helps distinguish a contained eyelid blockage from infection that is spreading.

Arrange prompt clinical advice if the redness or swelling is expanding, the eyelid is becoming harder to open, or discomfort is worsening. Do not squeeze or pierce the stye, share towels or eye products, or apply leftover antibiotics. Keep hands clean, avoid contact lenses and eye makeup, and use a clean warm compress only if it feels comfortable. A clinician may recommend treatment after checking the eyelid and surrounding skin.

Seek urgent care for vision changes, pain when moving the eye, a bulging eye, severe headache, marked facial swelling, confusion, faintness, or a high temperature. These symptoms can signal infection involving deeper tissues or a serious systemic illness. Fever, painful skin, skin redness, and skin swelling can help describe the change to a clinician.

Ask whether the infection is limited to the eyelid, whether you need prescription treatment, how to monitor the edge of the redness, and when it is safe to resume contact lenses or eye makeup.
