Pregnancy is a wild ride for your skin. One minute you've got that "glow" everyone talks about, and the next, you’re staring at a painful, red lump in the mirror that definitely isn't just a hormonal zit. It’s a boil. Finding boils during pregnancy while pregnant is surprisingly common, yet almost no one puts it in the baby books. It's frustrating. It's painful. And honestly, it’s the last thing you want to deal with when you’re already navigating back pain and swollen ankles.
A boil—technically called a furuncle—is basically a deep-seated skin infection that starts in a hair follicle or an oil gland. It usually starts as a firm, tender spot and then slowly fills with pus as your body tries to fight off the bacteria. While they can pop up anywhere, they love places with friction or sweat, like your armpits, groin, or even your breasts.
Why Your Body Is Suddenly Prone to These Lumps
Why now? It feels unfair.
The primary culprit is often Staphylococcus aureus. This is a bacteria that lives on many people's skin without causing a single issue. But pregnancy changes your internal chemistry. Your immune system shifts—it’s not exactly "weaker," but it’s modulated so your body doesn't reject the baby. This shift can sometimes make you more susceptible to common skin infections.
Then there are the hormones. Pregnancy hormones ramp up your oil production. More oil means more clogged pores. When a pore gets blocked and bacteria get trapped inside, you’ve got a recipe for a boil. Plus, as your body grows, you might experience more skin-on-skin friction in areas like the inner thighs or under the breasts. This chafing creates tiny micro-tears in the skin, giving bacteria an easy "in."
Gestational diabetes is another factor doctors look at. High blood sugar levels can make it harder for your body to fight off skin infections. If you are experiencing recurrent boils during pregnancy while pregnant, your OB-GYN might want to double-check your glucose levels just to be safe. It’s all connected.

A regular pimple is usually superficial. It might be annoying, but it doesn't usually throb. A boil is different. It’s deeper. It’s often much more painful to the touch. You’ll notice the skin around it getting red and swollen. As it "ripens," it develops a white or yellow center.
Sometimes, multiple boils cluster together. This is called a carbuncle. If you notice a cluster, or if you start feeling feverish and chilled, that’s a sign the infection might be spreading. Don't ignore that.
Safe Ways to Manage Boils at Home
First rule: Do not squeeze it.
I know it’s tempting. You want the pressure gone. But squeezing a boil during pregnancy can push the infection deeper into your tissues or even into your bloodstream. That’s bad news for you and potentially risky for the baby if the infection becomes systemic (sepsis).
Heat is your best friend. Basically, you want to encourage the boil to drain on its own. Soak a clean washcloth in warm water—not scalding—and hold it against the boil for 10 to 15 minutes. Do this three or four times a day. The heat increases blood flow to the area, which brings more white blood cells to fight the infection and helps soften the skin so the boil can eventually pop naturally.
Keep it clean.
Use a mild, fragrance-free antibacterial soap. Avoid scrubbing. Just gently wash the area and pat it dry with a clean towel. You don't want to spread the bacteria to other parts of your body.

Dressings matter.
Once the boil starts draining, cover it with a sterile bandage. This keeps the gunk from getting on your clothes and prevents you from touching it. Change the bandage frequently.
When to Call Your Doctor
Most boils resolve themselves in a week or two with home care. However, pregnancy means you have to be a bit more cautious.
If the boil is on your face, spine, or near your genitals, call your doctor. These areas are more sensitive and prone to complications. Also, if the boil hasn't improved after five days of warm compresses, or if it’s getting significantly larger and more painful, you need a professional opinion.
Doctors have a few ways to handle this. They might perform a small incision and drainage (I&D). They numb the area, make a tiny nick, and let the pus out. It sounds gross, but the relief is almost instant.
Can you take antibiotics while pregnant?
Yes. If the infection is stubborn, your doctor might prescribe antibiotics. They will choose ones that are "Category B"—meaning they are generally considered safe for use during pregnancy. Common choices include Cephalexin or certain types of Penicillin. Always finish the entire course, even if the boil looks better after two days.
Preventing the Next One
You can't control your hormones, but you can control your skin environment.

Wear loose-fitting clothes. Breathable fabrics like cotton are way better than synthetics that trap sweat. If you’re dealing with "chub rub" or friction, use a pregnancy-safe anti-chafe balm or a little cornstarch-based powder to keep things dry.
Handwashing is basic but huge. Since Staph is often spread by touch, washing your hands frequently can prevent you from moving bacteria into a fresh pore. Also, don't share towels or razors with anyone else in the house right now.
Dietary and Lifestyle Nuances
Some experts suggest that a diet high in processed sugars can contribute to skin inflammation. While you're already managing pregnancy cravings, try to lean into anti-inflammatory foods. Think berries, leafy greens, and plenty of water. Staying hydrated keeps your skin barrier healthier, which makes it harder for infections to take hold.
Iron levels are also worth mentioning. Some studies have linked chronic boils to iron deficiency anemia, which is very common in the second and third trimesters. If your blood work shows you're low on iron, your doctor's recommendation for a supplement might actually help your skin issues too.
What to Do Right Now
If you're currently dealing with boils during pregnancy while pregnant, take a deep breath. It’s a temporary skin glitch.
- Start the warm compresses immediately. Use a fresh cloth every single time to avoid re-infecting the area.
- Audit your wardrobe. Switch to the loose, "ugly" cotton undies or the flowy dress. Your skin needs to breathe.
- Track your temperature. If you feel "off" or run a fever over 100.4°F, call your OB-GYN or midwife right away.
- Check your prenatal vitamins. Ensure you aren't missing doses, as zinc and vitamin C play roles in skin repair.
- Resist the urge to "self-surgery." No needles, no squeezing. Let the heat do the work or let a professional handle the drainage.
Managing skin infections during these nine months is about patience and hygiene. Once your hormone levels stabilize post-birth, these issues typically vanish as quickly as they appeared. Focus on keeping the area clean and keeping your stress levels down—your body is already doing a lot of heavy lifting.
