Most cysts don’t need emergency treatment, but they rarely go away entirely on their own. The right approach depends on the type of cyst, whether it’s causing symptoms, and whether it shows signs of infection. Some cysts respond well to simple home care, others need to be drained or surgically removed, and a few just need to be left alone and monitored.
Home Care That Can Help
For a small, painless skin cyst (the most common kind people notice), 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. Use water no hotter than bath temperature. This can reduce discomfort and encourage the cyst to drain on its own, though it won’t always make it disappear completely.
Keep the area clean and avoid tight clothing or anything that rubs against the cyst. If it’s on your wrist or hand and you suspect a ganglion cyst (a firm, rubbery bump near a joint), immobilizing the joint with a brace or splint can sometimes help. Activity tends to make ganglion cysts grow, so resting the joint may allow the cyst to shrink and relieve pressure on nearby nerves.
What you should not do is try to squeeze, pop, or puncture a cyst yourself. This is one of the clearest warnings in dermatology. Puncturing a cyst at home can push bacteria deep into surrounding tissue. For ganglion cysts near joints, the risk is especially serious: infection from a home puncture has a short, direct route into the joint itself, which can lead to a severe joint infection that’s far worse than the original cyst.
Over-the-Counter Products
Drawing salves containing ichthammol (sometimes called “black ointment”) are a common home remedy. Ichthammol does have anti-inflammatory and antimicrobial properties, and it’s available without a prescription, typically as a 20% ointment. However, its effectiveness for cysts hasn’t been proven in clinical studies. It may offer mild symptom relief for surface-level inflammation, but it won’t dissolve a cyst wall or prevent recurrence. Think of it as a comfort measure, not a cure.
Signs a Cyst Is Infected
A cyst that becomes red, warm, increasingly painful, or starts leaking cloudy or foul-smelling fluid is likely infected. Swelling or redness extending more than a few centimeters beyond the cyst itself is a more serious sign. If you develop a fever alongside these symptoms, or notice red streaks spreading outward from the cyst, that suggests the infection is moving beyond the local area and needs prompt medical attention. Infected cysts typically require drainage and may need antibiotics, particularly if there are systemic signs of infection like fever or an elevated white blood cell count.
Drainage vs. Surgical Removal
When a cyst needs professional treatment, your provider will typically choose between two approaches: draining it or removing it entirely. Both are done in an office setting with local anesthesia, so you won’t feel pain during the procedure.
Drainage is the simpler option. The provider cleans the skin, numbs the area, makes a small cut, and drains the contents. The opening is then covered with gauze. This works well for immediate relief, especially if the cyst is infected and needs to be decompressed. The downside: drainage is not a permanent fix. Because the cyst’s inner lining (the sac) remains in place, the cyst can fill back up over time. Recurrence rates after incomplete removal are roughly 21%, about seven times higher than when the entire cyst is taken out.
Surgical excision removes the entire cyst in one piece, including the sac. The incision is typically larger, and the wound is closed with stitches. This approach drops the recurrence rate to around 3%. If you’ve had the same cyst drained more than once, full excision is usually the better long-term solution.
Steroid Injections for Inflamed Cysts
For cysts that are severely inflamed but not infected, a provider may inject a corticosteroid directly into the cyst. This calms the inflammation without surgery. The injections can be repeated every four to eight weeks if needed, and the total volume per session is kept small. This approach is more common for certain types of inflammatory skin lesions and cystic acne than for standard skin cysts, but it’s an option when inflammation is the main problem and the cyst doesn’t need to be removed right away.
When Treatment Depends on the Cause
Not all cysts are the same, and the type you have changes the treatment strategy entirely.
Skin cysts (epidermal or sebaceous cysts) sit just under the skin and are filled with keratin, a thick, cheese-like material. These are the ones most people picture when they think “cyst.” They’re treated with the drainage or excision approaches described above.
Ganglion cysts form near joints or tendons, most often on the wrist. They’re filled with clear, jelly-like fluid. Many ganglion cysts are painless and need no treatment at all. If one does cause pain or limits joint movement, a provider can aspirate (draw out) the fluid with a needle, though the cyst often returns. Surgical removal involves taking out the cyst along with the stalk that connects it to the joint or tendon. Even after surgery, ganglion cysts can occasionally come back.
Baker’s cysts form behind the knee and are almost always a symptom of something else, usually arthritis or a knee injury. Extra fluid produced by the damaged joint pools behind the knee and creates the cyst. The treatment here isn’t focused on the cyst itself. Instead, your provider treats the underlying knee problem. Once the joint damage heals or the inflammation is managed, the cyst typically resolves on its own.
What Recovery Looks Like
After a simple drainage, recovery is straightforward. You’ll leave the office with gauze and a bandage over the site. Keep it clean, change the dressing as directed, and watch for signs of infection (increasing redness, warmth, or discharge). Most people return to normal activities quickly.
After surgical excision, you’ll have stitches that need to stay in place until the wound heals, typically one to two weeks depending on the location and size. The incision site may be sore for several days. Avoid strenuous activity that could stress the area, and follow your provider’s instructions on wound care and when to return for stitch removal.
The most important thing to understand about cyst treatment is that recurrence is the main challenge. If a cyst keeps coming back after drainage, it’s because the sac lining is still intact under your skin. Full surgical removal is the most reliable way to prevent that cycle.
