Skin and Soft Tissue Infections: What You Need to Know

If you’ve ever had a red, swollen bump that didn’t go away, you probably dealt with a skin and soft tissue infection (SSTI). These infections hit the skin, muscles, fat or connective tissue and can range from harmless pimples to serious conditions like cellulitis. The good news is most SSTIs are easy to spot early and treat fast, so you don’t end up in the ER.

Common Types of Skin and Soft Tissue Infections

Even though doctors lump them together under “SSTI,” each infection has its own quirks. Here are the ones you’ll hear about most often:

• Cellulitis – a diffuse, red, warm area that spreads quickly. It usually starts after a small cut or scrape lets bacteria in.
• Abscess – a painful, pus‑filled pocket under the skin. Think of a boil that gets bigger and tender.
• Impetigo – a contagious rash common in kids, showing as honey‑colored crusts on the face or hands.
• Erysipelas – similar to cellulitis but with sharply defined edges, often caused by Streptococcus.
• Necrotizing fasciitis – a rare “flesh‑eating” infection that spreads along fascia layers. It’s an emergency and needs surgery fast.

The symptoms usually include redness, swelling, heat, pain, and sometimes fever or chills. If you notice any of these signs getting worse within 24 hours, it’s time to see a doctor.

How to Treat and Prevent SSTIs

Most mild infections can be managed at home with good hygiene and over‑the‑counter care, but antibiotics are often needed. Here’s a quick roadmap:

1. Clean the area. Use gentle soap and warm water. Pat dry – don’t rub.
2. Apply a topical antiseptic. Products with povidone‑iodine or chlorhexidine help kill surface bugs.
3. Watch for signs of spread. If redness expands beyond an inch, you feel feverish, or the pain intensifies, call your doctor.
4. Take prescribed antibiotics. Doctors usually pick oral options like cephalexin or clindamycin. Finish the full course even if you feel better.
5. Drain abscesses when needed. A professional can safely pop an abscess; trying at home risks deeper infection.

Prevention is mostly about keeping your skin barrier strong:

• Moisturize dry patches to stop cracks.
• Cover cuts, blisters or insect bites with clean bandages.
• Avoid sharing personal items such as towels or razors.
• If you have diabetes or poor circulation, check your feet daily for tiny wounds.

In short, don’t ignore a sore that’s getting red or hot. Early treatment usually means simple antibiotics and a quick recovery. By staying clean, treating minor cuts fast, and seeing a clinician when symptoms jump, you can keep skin and soft tissue infections at bay.
