Most bumps on the eyelid are styes. A stye is an inflamed oil gland on the edge of your eyelid, where the lash meets the lid. It appears as a red, swollen bump that looks like a pimple. It is often tender to the touch.
Bump on the eyelid; Stye; Hordeolum
A stye is caused by a blockage of one of the oil glands in the eyelids. This allows bacteria to grow inside the blocked gland. Styes are a lot like common acne pimples that occur elsewhere on the skin. You may have more than one stye at the same time.
Styes most often develop over a few days. They may drain and heal on their own. A stye can become a chalazion, which occurs when an inflamed oil gland becomes fully blocked. If a chalazion gets large enough, it can cause trouble with your vision.
In most cases, your health care provider can diagnose a stye just by looking at it. Tests are rarely needed.
To treat eyelid bumps at home:
Apply a warm, wet cloth to the area for 10 minutes. Do this four times a day.
Do NOT attempt to squeeze a stye or any other type of eyelid bump. Let it drain on its own.
Do NOT use contact lenses or wear eye makeup until the area has healed.
For a stye, your doctor may:
Prescribe antibiotic ointment
Make an opening in the stye to drain it (Do NOT try this at home)
Styes often get better on their own. However, they may return.
The outcome is almost always excellent with simple treatment.
Sometimes, the infection may spread to the rest of the eyelid. This is called eyelid cellulitis and may require oral antibiotics.
When to Contact a Medical Professional
Call your health care provider if:
You have problems with your vision
The eyelid bump worsens or does not improve within a week or two of self-care
The eyelid bump or bumps become very large or painful
You have a blister on your eyelid
You have crusting or scaling of your eyelids
Your whole eyelid is red, or the eye itself is red
You are very sensitive to light or have excessive tears
Another stye comes back soon after successful treatment of a stye
Your eyelid bump bleeds
Always wash your hands very well before touching the skin around your eye. If you are prone to getting styes or have blepharitis, it may help to carefully clean off excess oils from the edges of your lids. To do this, use,a solution of warm water and no-tears baby shampoo.
