A stye is a painful red bump on the eyelid caused by an infection of an oil gland. Most improve with warm compresses, but persistent or recurrent lumps should be evaluated by an eye specialist.
Is This a Stye? How to Tell — and When It’s Something Els
You woke up with a red, tender lump on your eyelid. It hurts to blink. You are fairly sure it is a stye — and you may well be right. But a stye, a chalazion, and meibomian gland dysfunction (MGD) are three different conditions that look similar and get confused constantly, including by people who have had them before.
I see patients who have been treating a chalazion with warm compresses for six months, expecting it to behave like a stye. I see others who dismiss a persistently blocked lid gland as something that will pass. Knowing which one you have changes what you do next.
This article helps you identify your eyelid lump accurately, understand what causes it, and know when to stop waiting and come in.
Quick Answer: A stye is a painful, red, pus-filled lump that forms at the edge of the eyelid, usually from a bacterial infection of a lash follicle or oil gland. It typically resolves in 7 to 14 days with warm compresses. A chalazion is a firm, usually painless lump sitting further back on the lid — it is a blocked meibomian gland, not an infection, and often needs a clinic procedure to resolve. MGD is the underlying gland dysfunction that makes both conditions more likely to recur.

Stye, Chalazion, or MGD: What Is the Difference?
These three conditions share the same anatomy — the eyelid’s oil-producing glands — but differ in cause, feel, and treatment.
A stye (also called a hordeolum) is an acute infection. It forms fast, hurts, and often has a visible yellow head. A chalazion is a chronic blockage without infection. It develops slowly, sits deeper in the lid, and feels like a hard pea under the skin. MGD is not a lump at all — it is a long-term dysfunction of the meibomian glands that creates the conditions for both styes and chalazia to keep coming back.
Stye
| Symptom | What It Means | What To Do |
|---|---|---|
| Red, painful lump at lash line | Infected lash follicle or external oil gland (Zeis or Moll) | Warm compress 10 minutes, 4 times daily |
| Yellow or white head visible | Pus collecting — classic external hordeolum | Do not squeeze; let it drain on its own |
| Lump inside the eyelid, painful | Internal hordeolum — infected meibomian gland | Warm compress; see a doctor if no improvement in 5 days |
| Swelling spreads to surrounding lid | Infection spreading beyond the gland | See a doctor promptly — may need antibiotics |
| Recurring styes in same location | Blocked gland or underlying MGD | Requires lid hygiene assessment, not just treatment of current stye |
| Stye in a child | Same mechanism, but children rub eyes more and delay healing | Warm compress; see a doctor if no change in 48 hours |
Chalazion
| Symptom | What It Means | What To Do |
|---|---|---|
| Firm, round lump in mid-lid, not at lash line | Blocked meibomian gland — not an infection | Warm compress 10 minutes, 4 times daily for 4 to 6 weeks |
| Lump is painless or mildly tender | Chronic granulomatous inflammation, not acute | No antibiotics needed unless secondarily infected |
| Lump has been there over 6 weeks with no change | Unlikely to resolve without intervention | See an ophthalmologist for incision and curettage (I&C) |
| Lump pressing on eyeball, blurring vision | Mechanical pressure on cornea | See a doctor — this needs prompt attention |
| Recurrence after treatment | MGD driving repeated blockages | Treat the gland dysfunction, not just the lump |
| Large chalazion in a child | Can cause amblyopia if it distorts vision | Paediatric ophthalmology referral |
MGD (Meibomian Gland Dysfunction)
| Symptom | What It Means | What To Do |
|---|---|---|
| Gritty, burning eyes — worse in the morning | Thickened meibum blocking tear film stability | Warm compress daily + lid massage |
| Eyelids feel crusty or stuck on waking | Inspissated gland secretions | Lid hygiene twice daily with a clean cloth or lid wipe |
| Frequent styes or chalazia | MGD is the root cause — glands chronically blocked | Address MGD, not just individual lumps |
| Frothy or foamy tears at lid margin | Bacterial overgrowth on lid margin secondary to MGD | Tea tree oil lid scrubs if Demodex suspected; see a doctor |
| Reduced or absent oil expression from lids | Glands are atrophying | Ophthalmologist assessment — early intervention matters |
| Dry eye symptoms alongside lid problems | Tear film instability from poor meibum quality | Omega-3 supplements, warm compress, preservative-free drops |
How to Tell a Stye from a Chalazion at Home
Location matters most. A stye sits at or very close to the lash line. A chalazion sits higher up on the lid, away from the lashes, and you can often feel it as a distinct firm nodule under the skin.
Pain is the second clue. Styes hurt. Chalazia usually do not, unless they become secondarily infected.
Speed of onset is the third. If it appeared overnight and is throbbing, it is likely a stye. If you noticed it gradually over days or weeks, suspect a chalazion.
What To Do at Home
These measures work for both styes and chalazia in the early stages.
- Apply a warm compress for 10 minutes, four times a day. The compress must be genuinely warm — a flannel soaked in hot water and wrung out, or a clean heated eye mask. Warmth softens the blocked secretion and helps drainage.
- After the compress, gently massage the lid in the direction of the lashes to encourage the gland to express.
- Do not squeeze, pop, or pierce the lump. This risks spreading infection and causing scarring.
- Remove all eye makeup while the lump is active. Mascara and eyeliner worsen gland blockage.
- Do not wear contact lenses until the stye has fully resolved.
- If you have recurrent episodes, start daily lid hygiene as a long-term habit — not just when a lump appears.
When To See a Doctor
Do not wait if you notice any of the following:
- The lump is not improving after warm compresses
- A chalazion has been present for more than 2 weeks without change
- Swelling is spreading beyond the eyelid to the cheek or brow
- You have fever, significant pain, or the eyelid is hot to touch
- Vision is blurred or you feel pressure on the eye
- The lump is in a child and affecting how the eye opens or moves
- You have had the same lump treated and it has returned in the same spot
- You are on immunosuppressants, have diabetes, or have had previous eyelid surgery
A lump that keeps returning in the same location needs a biopsy to rule out a sebaceous gland carcinoma. This is rare, but I do not skip it — and neither should your doctor.
Medical Treatment Options
For Styes
Most styes resolve with warm compresses alone. If they do not, an ophthalmologist may prescribe a short course of topical antibiotic drops or ointment. Oral antibiotics are rarely needed unless the infection has spread. A stye that is pointing but not draining can be lanced under local anaesthetic in a clinic setting — a quick, painless procedure.
For Chalazia
A chalazion that has not responded to four to six weeks of warm compresses needs an incision and curettage (I&C). This is a minor procedure done under local anaesthetic in clinic. The lid is everted, a small incision made on the inside surface, and the granulomatous contents removed. It takes under 10 minutes. Recurrence after I&C is common if underlying MGD is not treated.
An intralesional steroid injection is an alternative for patients who prefer to avoid surgery, or for chalazia in cosmetically sensitive locations. It works well for soft, early chalazia.
For MGD
MGD is a chronic condition and needs ongoing management, not just treatment of individual episodes. The approach includes:
- Daily warm compress and lid massage (long-term, not just during flares)
- Lid hygiene with baby shampoo or a dedicated lid scrub, twice daily
- Omega-3 fatty acid supplementation — evidence supports this for meibum quality
- In-clinic treatments including meibomian gland expression, intense pulsed light (IPL) therapy, or LipiFlow for more severe cases
- Demodex treatment with tea tree oil lid scrubs if mite infestation is contributing
Frequently Asked Questions
Can I pop a stye at home?
No. Squeezing or piercing a stye risks spreading the infection deeper into the lid or into surrounding tissue. Let it drain on its own with warm compresses.
How long does a stye take to go away?
Most styes resolve in 7 to 14 days with consistent warm compresses four times daily. A lump that persists beyond two weeks needs a clinic review.
Is a chalazion the same as a stye?
No. A stye is an acute bacterial infection at the lash line. A chalazion is a chronic blocked gland, usually painless, sitting deeper in the lid.
Why do I keep getting styes?
Recurrent styes usually indicate underlying meibomian gland dysfunction (MGD), which blocks glands repeatedly. Treating the MGD — not just each individual stye — breaks the cycle.
Can MGD cause a stye?
Yes. MGD thickens the oil secretions in the meibomian glands, making blockage and secondary infection more likely. It is the most common underlying cause of recurrent styes and chalazia.
When does a chalazion need surgery?
A chalazion needs incision and curettage if it has not responded to warm compresses after four to six weeks, is large enough to press on the eye, or is affecting vision or lid position.
Key Takeaways
- A stye is painful, fast-forming, and sits at the lash line — it is an infection
- A chalazion is firm, usually painless, and sits deeper in the lid — it is a blockage, not an infection
- MGD is the root cause of most recurrent styes and chalazia
- Warm compresses four times daily are the first treatment for both styes and chalazia
- Never squeeze or pop an eyelid lump
- A chalazion lasting more than six weeks needs a clinic procedure
- Recurrent lumps in the same spot need a biopsy to rule out malignancy
Book a Consultation
If your eyelid lump has not resolved in two weeks, keeps coming back, or is affecting your vision or comfort, I would encourage you to come in for an assessment. Styes and chalazia are very treatable — but they need the right diagnosis first, particularly if MGD is driving the pattern.
