An internal stye is a painful, red bump that forms on the inside of your eyelid when one of the oil-producing glands deep within the lid becomes infected. The good news: most internal styes clear up within one to two weeks with consistent home care. The primary treatment is warm compresses applied several times a day, though styes that don’t respond may need a quick in-office procedure to drain.
What Causes an Internal Stye
Your eyelids contain dozens of tiny oil glands called meibomian glands, which sit within the firm tissue (tarsal plate) of the lid itself. These glands produce an oily layer that keeps your tears from evaporating too quickly. When one of these glands gets blocked and bacteria move in, the result is an internal stye, technically called an internal hordeolum.
The culprit in 90% to 95% of cases is Staphylococcus aureus, a common bacterium that already lives on your skin. Because the infection sits deeper inside the eyelid rather than along the lash line, internal styes tend to be more painful and slower to resolve than external ones. You’ll usually notice a tender, swollen spot on the inner surface of the lid, sometimes visible only when you gently flip the eyelid.
Warm Compresses: The Core Treatment
Warm compresses are the single most effective home treatment for an internal stye. The heat softens the blocked oil inside the gland, encourages drainage, and increases blood flow to the area so your immune system can fight the infection faster. Hold a clean, warm (not scalding) damp cloth against the closed eye for about five minutes at a time. Repeat this three to four times throughout the day.
A few tips to get the most out of each session. Rewet the cloth as it cools, since a lukewarm compress won’t do much. Microwavable eye masks designed for dry eye also work well because they hold heat longer. After each compress session, you can gently massage the eyelid from the base toward the lid margin using light pressure. This helps push softened material out of the blocked gland. Always wash your hands before touching the area.
If the stye hasn’t improved noticeably within about a week of consistent compress use, it’s time to see an eye care provider.
What Not to Do
It’s tempting to squeeze or try to pop an internal stye the way you might a pimple. Don’t. Squeezing a stye can push the infection deeper into the eyelid tissue, potentially causing a more severe infection, scarring, changes in skin color around the lid, or even a scratch on the surface of the eye (corneal abrasion). Let the warm compresses do the work. If the stye is going to drain, it will do so on its own once the blocked gland softens enough.
You should also avoid wearing contact lenses or eye makeup on the affected eye until the stye has fully resolved. Both can introduce more bacteria and slow healing.
Over-the-Counter Stye Products
You’ll find OTC stye drops and ointments at most pharmacies. It’s worth knowing that many of these are homeopathic products designed only to temporarily relieve symptoms like redness, burning, and tearing. They are not antibiotics and will not cure the infection itself. The packaging typically states this directly. They can take the edge off discomfort, but warm compresses remain far more effective at actually resolving the stye.
Over-the-counter pain relievers like ibuprofen or acetaminophen can help manage the soreness, especially during the first few days when swelling tends to peak.
When You Need Medical Treatment
If your internal stye persists beyond one to two weeks, grows larger, or becomes increasingly painful despite consistent warm compresses, a doctor can prescribe antibiotic ointment or drops to help clear the bacterial infection. Because internal styes sit deep within the lid, topical antibiotics alone don’t always penetrate well enough, which is why warm compresses remain the first line of treatment even in a clinical setting.
A stye that hardens into a firm, painless lump has likely transitioned into a chalazion, which is a blocked gland without active infection. Chalazions can linger for weeks or months. If one persists beyond one to two months, your eye doctor may recommend a minor drainage procedure.
What Happens During a Drainage Procedure
Incision and drainage sounds more dramatic than it is. The procedure takes about 15 to 20 minutes in a doctor’s office. An ophthalmologist numbs the eyelid with a local anesthetic, makes a small incision on the inner surface of the lid (so there’s no visible scar), and drains the trapped fluid and material from the gland. Afterward, you’ll typically wear a pressure patch briefly and use a prescribed antibiotic cream or drops for about a week to prevent reinfection. Most people return to normal activities quickly.
Signs of a Serious Complication
In rare cases, an eyelid infection can spread to the tissue surrounding the eye, a condition called orbital cellulitis. This requires emergency treatment. Get to an emergency room if you develop any of the following alongside your stye: a fever, a bulging eye, significant swelling extending beyond the eyelid to the surrounding skin, pain when moving the eye, or any change in vision. Children are particularly vulnerable to this complication, so take a child with these symptoms to the ER immediately.
Preventing Recurrent Internal Styes
Some people get internal styes repeatedly, often because their meibomian glands are prone to clogging. A condition called blepharitis, or chronic inflammation of the eyelid margins, is one of the most common underlying causes. A daily eyelid hygiene routine can make a significant difference.
The goal is twofold: remove debris and bacteria from the lid margin, and keep the meibomian glands flowing freely. Start with a warm compress for about five minutes to loosen any dried oil or crust. Then gently massage the lids from the base toward the lash line to express thickened oil from the glands. Finally, clean the lid margin with a dedicated eyelid cleansing product. These come as pre-moistened pads, foams, or solutions and are specifically formulated to be safe near the eyes.
Plain soap and water aren’t a great substitute. Research published in Clinical Ophthalmology found that soap doesn’t effectively reduce bacterial buildup on the eyelids and can actually damage the protective oil layer of your tears, causing stinging and making long-term compliance difficult. Purpose-made lid cleansers are gentler and more effective for daily use. You can find them at most pharmacies, often marketed for blepharitis or dry eye care.
