What is Cellulitis?

Cellulitis is a common yet potentially serious bacterial skin infection. It occurs when bacteria enter the skin through a cut, scrape, insect bite, or surgical wound, causing redness, swelling, and pain. If left untreated, cellulitis can spread rapidly and lead to dangerous complications.

At BASS Medical Group, our primary care providers (PCPs) are trained to diagnose and treat cellulitis early—helping you avoid unnecessary risk.

What Causes Cellulitis?

Cellulitis is usually caused by two types of bacteria:

• Streptococcus – Often responsible for spreading quickly across the skin.
• Staphylococcus – Including MRSA, which can be more resistant to antibiotics.

Bacteria enter through breaks in the skin and infect the deeper layers. While cellulitis isn’t contagious, the infection can spread to the bloodstream or lymph nodes if not treated promptly.

Common Symptoms of Cellulitis

Symptoms often appear on the legs or feet but can develop anywhere. Watch for:

• Redness and warmth in the affected area
• Swelling or tenderness
• Skin that feels tight or stretched
• Pain at the site
• Blisters or abscesses
• Fever or chills (in more serious cases)

When to Seek Emergency Care: If you experience a rapidly spreading rash, fever, or severe pain, seek immediate medical attention. Cellulitis can become life-threatening if it progresses to the bloodstream.

Risk Factors for Developing Cellulitis

While anyone can develop cellulitis, the following increase your risk:

• Recent surgery, injury, or wounds
• Skin conditions like eczema, athlete’s foot, or ulcers
• Diabetes or poor circulation
• Weakened immune system
• Intravenous drug use

Is Cellulitis Dangerous?

Yes—if left untreated, cellulitis can lead to serious complications such as:

• Sepsis
• Endocarditis (heart infection)
• Bone infections (osteomyelitis)
• Necrotizing fasciitis (flesh-eating infection)
• Permanent swelling (lymphedema) due to damaged lymph nodes

Cellulitis Treatment Options

The most common treatment is oral antibiotics. For more severe cases, intravenous (IV) antibiotics or surgical drainage may be required. Additional treatments may include:

• Over-the-counter pain relievers (e.g., ibuprofen)
• Cold compresses to reduce swelling
• Wound care and elevation of the affected area

If caught early, most cases of cellulitis resolve with proper medical care.

Prevention Tips: How to Avoid Cellulitis

To reduce your risk of cellulitis, especially if you have a cut or skin injury:

• Wash wounds gently with soap and water daily
• Apply antibiotic ointment and cover with a clean bandage
• Avoid scratching or picking at your skin
• Moisturize dry skin to prevent cracking
• Wear protective footwear and gloves if prone to injury
• Treat athlete’s foot and other skin conditions promptly

People with diabetes should take extra precautions by inspecting their feet daily and trimming toenails carefully.

When Should You See a Doctor?

You should contact your doctor if you notice:

• A red, warm, swollen area that is growing
• Fever or chills with skin symptoms
• Pain that worsens over time
• Pus, drainage, or foul-smelling wounds

Our primary care providers at BASS Medical Group can evaluate and treat cellulitis early—and refer you to wound care or infectious disease specialists if needed.
