Most cysts don’t need emergency treatment, but they rarely go away on their own. A small, painless cyst under the skin can often be managed at home while you decide whether to pursue removal, while an inflamed or infected cyst typically needs professional drainage or excision. The right approach depends on the type of cyst, its size, and whether it’s causing symptoms.
Home Treatment for Skin Cysts
If you have a small, non-infected cyst that isn’t bothering you much, warm compresses are the standard first step. Apply a warm, wet washcloth to the area for 20 to 30 minutes, three to four times a day. The heat increases blood flow to the area and can help the cyst drain on its own or reduce swelling. This works best for superficial skin cysts like epidermoid cysts (sometimes called sebaceous cysts) that sit just beneath the surface.
What you should never do is squeeze or pop a cyst yourself. Unlike a pimple, a cyst has a sac wall underneath the skin. Squeezing it can push its contents deeper into surrounding tissue, trigger inflammation, or introduce bacteria that lead to infection. If warm compresses don’t improve things within a week or two, or if the cyst is growing, it’s time to see a provider.
How to Tell If a Cyst Is Infected
A typical cyst feels like a round, firm lump under the skin. It’s usually painless and moves slightly when you press on it. An infected cyst, by contrast, turns red, feels warm to the touch, becomes swollen and tender, and may start leaking pus. At that point it’s functioning more like an abscess, a pocket of bacterial infection that needs drainage.
The distinction matters because an infected cyst won’t resolve with warm compresses alone. Drainage is the primary treatment. For small abscesses under 2 cm that are already draining on their own, close monitoring can sometimes be enough. Larger or worsening infections need incision and drainage by a clinician. Antibiotics on top of drainage cut the rate of treatment failure roughly in half, from about 16% with drainage alone to 8% with antibiotics added, though many healthy patients with a single uncomplicated abscess do fine without them.
In-Office Procedures
For a cyst that keeps coming back or one that’s cosmetically bothersome, a provider can offer several options depending on the situation.
Steroid Injections
When a cyst is inflamed but not infected, a steroid injection directly into the lump can shrink it quickly. This is common for inflamed acne cysts. The injection reduces swelling and pain within a day or two, though it doesn’t remove the cyst wall, so the cyst may eventually return.
Needle Aspiration
A provider inserts a needle into the cyst and draws out the fluid. This deflates the cyst and provides immediate relief, especially for ganglion cysts on the wrist or hand. The downside is a high recurrence rate. Studies find that 60% to 95% of ganglion cysts return after aspiration because the cyst wall remains intact and refills over time. Aspiration works best as a temporary measure or for people who want to avoid surgery.
Incision and Drainage
The provider numbs the area, makes a small cut, and squeezes out the cyst’s contents. This resolves the immediate problem but, like aspiration, leaves the cyst wall behind. Recurrence is common for this reason. Incision and drainage is most useful for infected cysts that need urgent relief.
Surgical Excision
Complete removal of the cyst, including its entire sac wall, is the only way to prevent it from coming back. This is a minor outpatient procedure done under local anesthesia.
Traditional excision involves cutting the skin over the cyst, removing the whole sac, and closing the wound with stitches. This is highly effective but leaves a scar roughly proportional to the cyst’s size. For cysts on the face, minimally invasive techniques produce significantly smaller scars. One approach uses a tiny 2 to 3 mm opening (made with a laser or small punch tool) to extract the cyst contents and then scrape out the sac wall through that same hole. In a comparison study, the average scar from this method measured about 3 mm at one year, compared to over 12 mm with traditional excision.
The timing matters too. Providers generally prefer to excise a cyst when it’s not actively inflamed or infected, since inflammation makes it harder to cleanly remove the entire wall and increases the chance of recurrence. If your cyst is currently red and swollen, a provider may drain it first, let it calm down for a few weeks, and then schedule the excision.
Recovery After Cyst Removal
Recovery from excision is straightforward but requires consistent wound care. You’ll leave the office with a dressing over the site and will need to change it daily or every few days, depending on the wound’s location and size. Stitches come out anywhere from 3 to 14 days after the procedure.
During healing, wash your hands before and after touching the area, and inspect the wound daily for signs of infection like increased swelling, pus, or color changes. Avoid tight clothing that rubs against the site, and skip activities like running, lifting, or anything that stretches the skin around the wound. If bleeding occurs, press a clean cloth firmly against the incision and hold it there until the bleeding stops. Most people return to normal activities within a week or two, depending on where the cyst was located.
Ovarian and Internal Cysts
Not all cysts sit under the skin. Ovarian cysts are extremely common and most resolve without treatment. For simple fluid-filled ovarian cysts, the approach depends largely on size. Cysts under 3 cm in postmenopausal women are typically monitored with periodic ultrasound rather than treated. Research following over 200 of these small cysts found that nearly all remained stable over an average follow-up of more than five years, and about 18% resolved entirely on their own.
Larger cysts, those with unusual features on imaging, or cysts causing significant pain may require surgical removal, usually through a minimally invasive laparoscopic procedure. In premenopausal women, many functional ovarian cysts disappear within one to three menstrual cycles, so a provider will often recommend simply rechecking with an ultrasound before considering intervention.
When Removal Is Worth It
Skin cysts are almost never dangerous. The rate of a common epidermoid cyst transforming into skin cancer is between 0.011% and 0.045%, making it an extraordinarily rare event. So the decision to remove a cyst is usually about comfort and convenience rather than safety. Removal makes sense if the cyst keeps getting infected, is in a spot where it gets irritated by clothing or movement, is cosmetically bothersome, or is painful. If none of those apply, leaving it alone and monitoring for changes is perfectly reasonable.
