An internal stye is a small, painful bump that forms on the inside of your eyelid when one of the oil-producing glands (called meibomian glands) becomes infected. Most internal styes resolve within one to two weeks with consistent home treatment, though they can feel more painful than external styes because they press directly against your eyeball.
Why Internal Styes Are Different
External styes form at the base of an eyelash, essentially a pimple on the outer edge of your lid. Internal styes develop deeper, inside the eyelid itself. The meibomian glands that line the inner lid produce an oily layer that keeps your tears from evaporating too quickly. When one of these glands gets blocked, its oily secretions thicken and stagnate, creating a perfect environment for bacteria to multiply. The result is a red, swollen lump you can see when you flip your eyelid, and it often hurts more than an external stye because of its position against the eye’s surface.
The underlying cause is usually chronic inflammation of the meibomian glands, where the gland openings become clogged with thickened secretions over time. People with a history of blepharitis (ongoing eyelid inflammation) are especially prone to recurrences.
Warm Compresses: The Core Treatment
The most effective thing you can do at home is apply warm, moist compresses to the affected eye for 5 to 10 minutes, 3 to 6 times a day. The heat softens the hardened oil plugging the gland, allowing it to drain naturally. This is the single most important step, and doing it consistently makes the difference between a stye that clears in a week and one that lingers for months.
Use a clean washcloth soaked in warm water and wring it out. The cloth cools quickly, so re-soak it every couple of minutes to keep the temperature steady. Don’t heat a wet cloth in the microwave, as it can develop hot spots that burn the delicate eyelid skin. Alternatively, you can buy a microwavable eye mask designed for even heat distribution.
After each compress session, gently massage the eyelid with a clean finger in a circular motion toward the gland opening. This helps push the trapped oil out. Some people also find it helpful to clean the eyelid margin with diluted baby shampoo on a cotton swab to keep the area free of debris.
What Not to Do
Do not try to squeeze or pop an internal stye. It might look like it has a visible head, but forcing it open carries real risks: severe infection that can spread to surrounding tissue, permanent scarring or pigment changes on your eyelid, and corneal abrasion from the pressure or from material getting into your eye. The gland needs to drain through its natural opening, and warm compresses are the safest way to make that happen.
While the stye is active, stop wearing contact lenses. Lenses trap bacteria against the eye and can irritate the swollen area. Switch to glasses until the bump is completely gone. You should also avoid eye makeup during this time, as cosmetics can introduce more bacteria to an already-infected gland. Once the stye heals, throw away any eye makeup you used in the days before the stye appeared, particularly mascara and eyeliner. Don’t transfer old applicators into new product containers.
When You Need Medical Treatment
If your internal stye hasn’t improved after about a week of consistent warm compresses, it’s time to see an eye doctor. At that point, the infection may have walled itself off into a firm, painless nodule called a chalazion, which won’t respond to compresses alone.
Your doctor may prescribe antibiotic eye drops or ointment to clear the bacterial infection. Oral antibiotics are typically reserved for two situations: when the infection has spread beyond the stye into the surrounding skin (a condition called preseptal cellulitis), or when you have a history of multiple recurring styes with chronic gland inflammation. For recurrent cases, a low-dose antibiotic taken over several weeks can help reduce the underlying gland inflammation that keeps triggering new styes.
Incision and Drainage
If a stye or the chalazion it becomes persists for more than one to two months, a minor in-office procedure can drain it. Your doctor numbs the eyelid with a local anesthetic, flips it, and makes a small incision on the inner surface to release the trapped contents. The whole thing takes a few minutes.
Recovery is fast. Your eyelid may feel sore for a few days, but you can shower and go back to normal activities right away. Your doctor will likely place a pressure patch on the eye briefly and prescribe antibiotic drops or ointment for about a week to prevent reinfection. No stitches are needed because the incision is made on the inside of the lid, so there’s no visible scar.
Signs of a Serious Infection
Rarely, the infection from a stye can spread into the tissue surrounding the eye. This is called preseptal (periorbital) cellulitis, and it requires prompt medical attention. Watch for these warning signs:
- Fever alongside worsening eye swelling
- Pain and swelling spreading across the entire eye socket area, not just the bump itself
- Vision changes, such as blurriness or double vision
- Bulging of the eye forward from the socket
If the infection crosses deeper into the eye socket, it becomes orbital cellulitis, which is a medical emergency. Go to the emergency room if you or your child develops a fever with severe swelling around the entire eye, especially if the eye appears to be protruding or vision is affected.
Preventing Recurrence
If you’ve had one internal stye, you’re more likely to get another, particularly if the underlying gland inflammation hasn’t been addressed. A daily eyelid hygiene routine can significantly reduce your risk. Each morning, apply a warm compress for a few minutes to keep the meibomian gland oils flowing, then gently clean along the lash line with a dedicated lid scrub or diluted baby shampoo.
Avoid touching or rubbing your eyes with unwashed hands. Replace eye makeup every three to six months, and never share cosmetics. If you wear contact lenses, follow your prescribed replacement schedule strictly and clean them properly each night. People who get frequent styes sometimes benefit from omega-3 fatty acid supplements, which can improve the quality of meibomian gland secretions and reduce the thick, stagnant oil that leads to blockages.
