Skin Abscess Drainage in San Ysidro: When a Boil Needs Care

A tender red lump that keeps swelling, throbs when you sit or move, and starts to show a yellow-white tip is hard to ignore. Most small boils heal with simple home care, but some grow into a deeper pocket of pus that needs abscess drainage by a clinician. Here is how to tell the difference and when to be seen. In San Ysidro, Palm Urgent Care, San Ysidro offers minor procedures. Call ahead to confirm whether incision and drainage can be done during your visit.

Boil, Abscess or Something Else?

These terms overlap. Mayo Clinic describes a boil (also called a furuncle) as a painful, pus-filled bump that forms when bacteria infect one or more hair follicles, and a carbuncle as a cluster of boils that form a connected area of infection under the skin (Mayo Clinic). A skin abscess is the broader term: MedlinePlus defines it as a buildup of pus in or on the skin, which can start from a boil, an infected hair follicle or a minor wound.

Boils usually appear on the face, back of the neck, armpits, thighs and buttocks, and most are caused by Staphylococcus aureus (staph). The CDC reports that about 30% of people carry staph in their noses, and that staph infections can look like pimples, boils or other skin conditions. Some are caused by MRSA, a type of staph that can resist several antibiotics (CDC). Because a painful lump under the skin can resemble other problems, an exam is the most reliable way to know what you are dealing with.

When Warm Compresses Are Enough

A single, small boil often heals at home. Mayo Clinic recommends applying a warm washcloth or compress several times a day, for about 10 minutes each time, to help the boil rupture and drain more quickly (Mayo Clinic). According to MedlinePlus, boils usually need to open and drain in order to heal, which most often happens within 2 weeks. MedlinePlus also recommends these steps to keep the infection from spreading:

• Keep using warm, wet compresses after the boil opens, and change the dressing often.
• Wash your hands well before and after touching it.
• Do not reuse or share washcloths or towels, and wash linens that touched the area in hot water.
• Throw out used dressings in a sealed bag.

Signs You Need a Provider

Mayo Clinic advises seeing a doctor if you have more than one boil at a time. Mayo Clinic and MedlinePlus also list these reasons to have a boil checked:

• It is on your face or spine, or it affects your vision.
• It worsens rapidly, is extremely painful, or keeps getting bigger despite self-care.
• It comes with a fever, or red streaks spread out from the sore.
• It does not improve after 1 week of home treatment (MedlinePlus) or has not healed in two weeks (Mayo Clinic).
• It comes back after treatment.

Size matters as well. Mayo Clinic notes that a boil can grow to more than 2 inches (5 centimeters) across, and it lists incision and drainage as a treatment for larger boils and carbuncles. For a bump that may be MRSA, the CDC advises contacting a provider, especially with a fever or no improvement within 48 hours.

When to Go to the ER or Call 911

Rarely, bacteria from a boil or carbuncle enter the bloodstream and cause sepsis, Mayo Clinic explains. The CDC calls sepsis a life-threatening medical emergency and lists these signs:

• Confusion or disorientation
• Shortness of breath
• High heart rate or weak pulse
• Fever, shivering or feeling very cold
• Clammy or sweaty skin
• Extreme pain or discomfort

If a skin infection comes with signs like these, especially confusion, trouble breathing, or a racing or weak pulse, call 911 or go to the nearest emergency room. Do not wait for an urgent care visit. Redness that keeps spreading can also signal cellulitis, a deeper skin infection that MedlinePlus says should be checked by a provider right away.

Why You Should Never Squeeze or Lance It at Home

Mayo Clinic warns that pricking or squeezing a boil may spread the infection, and MedlinePlus says never to squeeze a boil or try to cut it open at home. For a bump that could be MRSA, the CDC gives the same advice: do not pick at or pop it, and cover the area with clean, dry bandages.

MedlinePlus lists spread of the infection in the same area, spread into the blood, and tissue death (gangrene) as possible complications of a skin abscess. Household needles and blades are not sterile, and deep pockets of pus can be hard to empty completely even in a clinic.

What In-Office Abscess Drainage Involves

Incision and drainage, often shortened to I&D, is a short procedure. Here is what to expect:

1. Exam and history. The clinician examines the lump and asks whether you have had boils before, whether you have a fever or chills, and whether you have artificial joints, heart valves or other implanted devices.
2. Numbing. MedlinePlus explains that numbing medicine is applied before the abscess is opened.
3. Opening and draining. A small incision lets the pus drain out.
4. Packing, if needed. Deep infections that cannot be completely drained may be packed with sterile gauze to soak up additional pus (Mayo Clinic).
5. Aftercare. You leave with a dressing and wound care instructions. Antibiotics are not always needed. Mayo Clinic says they are sometimes prescribed for severe or recurrent infections.

Bring a list of your medicines, including vitamins and over-the-counter products. For a first visit, read what to expect at a walk-in urgent care visit. You can also review all Palm Urgent Care services.

Repeat Infections, Lab Cultures and Diabetes

Mayo Clinic says a sample of the pus may be sent to a lab if you have recurring infections or one that has not responded to standard treatment. Many varieties of the bacteria that cause boils resist certain antibiotics, so lab testing helps your clinician choose one that will work. The San Ysidro clinic offers lab testing, and your clinician can explain whether a culture makes sense.

Mayo Clinic lists these risk factors for boils and carbuncles:

• Diabetes, which can make it harder for your body to fight bacterial skin infections
• A weakened immune system, for any reason
• Skin conditions such as acne or eczema, which damage the skin's protective barrier
• Close contact with a person who has a staph infection

If you have diabetes, have a painful boil checked sooner rather than later. To lower the chance of another infection, Mayo Clinic recommends washing your hands regularly, keeping cuts covered with sterile, dry bandages until they heal, and not sharing towels, razors, clothing or athletic equipment.

Frequently Asked Questions

Can urgent care drain an abscess?

Palm Urgent Care in San Ysidro offers minor procedures. Call ahead to confirm whether abscess drainage can be done during your visit. A provider can evaluate the abscess and, if needed, refer you. If a skin infection comes with signs of sepsis, such as confusion, trouble breathing or a racing or weak pulse, call 911 instead.

Will a boil go away on its own?

Often, yes. MedlinePlus says boils usually open and drain within 2 weeks with warm compresses. See a provider if the boil is on your face or spine, comes with a fever, or is not better after a week.

Does abscess drainage hurt?

MedlinePlus explains that numbing medicine is applied before the abscess is opened, so the procedure is designed to limit pain.

Do I need antibiotics for a boil or abscess?

Not always. Mayo Clinic says antibiotics are sometimes prescribed for severe or recurring infections. MedlinePlus adds that antibacterial soaps and creams cannot help much once a boil has formed.
