Cellulitis

Common and potentially serious bacterial skin infection causing red, swollen skin

Overview

Cellulitis is a bacterial skin infection that affects the deeper layers of the skin, including the dermis and subcutaneous tissues. It is typically caused by Staphylococcus or Streptococcus bacteria entering the skin through a cut, wound, or pre-existing skin condition. Prompt treatment is essential to prevent complications and promote healing.

Symptoms

The signs and symptoms of cellulitis may include:

  • Redness and swelling: The affected area becomes red, swollen, and tender to the touch.
  • Warmth and pain: The skin feels warm and may be accompanied by pain or discomfort.
  • Skin tightness: The affected area may feel tight or stretched.
  • Skin dimpling: In some cases, the skin may appear dimpled or pitted.
  • Fever and chills: Systemic symptoms like fever, chills, and fatigue may occur in severe cases.

Causes

Cellulitis occurs when bacteria enter the skin through a break in the skin barrier. Common causes include:

  • Cuts, scrapes, or wounds: Even small breaks in the skin can provide an entry point for bacteria.
  • Skin conditions: Conditions like eczema, athlete’s foot, or fungal infections can weaken the skin’s defense, making it more susceptible to infection.
  • Insect bites: Insect bites, particularly from spiders or ticks, can introduce bacteria into the skin.
  • Underlying medical conditions: People with weakened immune systems, diabetes, or circulation problems are at higher risk of developing cellulitis.

Treatment

Prompt treatment is important to control the infection and prevent its spread. Treatment options for cellulitis may include:

  • Antibiotics: Oral or intravenous antibiotics are prescribed to eliminate the bacteria causing the infection.
  • Elevation: Elevating the affected limb or area can help reduce swelling and promote drainage.
  • Warm compresses: Applying warm compresses to the area can help alleviate pain and promote healing.
  • Pain relievers: Over-the-counter pain relievers like acetaminophen or ibuprofen can help manage pain and reduce fever.

It’s crucial to complete the full course of prescribed antibiotics, even if symptoms improve, to ensure complete eradication of the infection.

Self-care

To aid in the recovery process and prevent recurrence, consider the following self-care measures:

  • Keep the area clean: Gently clean the affected area with mild soap and water, and cover it with a clean, dry bandage.
  • Avoid scratching or picking: Refrain from scratching or picking at the affected area to prevent further infection or complications.
  • Monitor for changes: Watch for any worsening symptoms, such as increased redness, swelling, or drainage, and consult a healthcare professional if needed.
  • Preventive measures: Take steps to prevent future infections, such as practicing good hygiene, treating underlying skin conditions, and protecting the skin from injuries.

If symptoms persist or worsen despite treatment, or if you develop fever or other concerning signs, seek medical attention for further evaluation and management.
