Skin Infections (Cellulitis, Abscess, and Impetigo)

Skin infections occur when bacteria enter the skin through small cuts, insect bites, or irritations, leading to redness, swelling, and pain. The most common types seen in urgent care include cellulitis (a deeper skin infection), abscesses (pockets of pus under the skin), and impetigo (a contagious surface rash, often in children).

At The Medical Group of New Jersey, our urgent care providers offer on-site wound evaluation, drainage procedures, and antibiotic therapy to promote healing and prevent complications.


Symptom Onset & Initial Evaluation

Skin infections can develop gradually over several days or appear suddenly following minor skin trauma or exposure. Common symptoms include:

  • Redness, warmth, or swelling in the affected area
  • Tenderness or localized pain
  • Pus, drainage, or crusting (especially with abscesses or impetigo)
  • Fever, fatigue, or chills in more advanced infections

During your visit, your provider at The Medical Group of New Jersey Urgent Care will review your symptom timeline, recent skin injuries, and any underlying medical conditions—such as diabetes or immune suppression—that could slow healing. A focused skin and soft-tissue exam helps determine how deep the infection is and whether drainage or further testing is needed.


Diagnosis

Diagnosis is usually based on the appearance of the affected skin and clinical examination. When needed, your provider may perform additional tests to confirm the diagnosis and guide treatment, including:

  • Wound culture or swab: Identifies the bacteria responsible for infection and determines which antibiotics will work best.
  • Ultrasound imaging: Detects abscesses or fluid collections that may require drainage.
  • Blood tests: Used in more severe cases to check for systemic infection or inflammation.

Treatment & Ongoing Management

Treatment focuses on controlling infection, reducing inflammation, and promoting healing.

  • Antibiotics: Topical antibiotics for mild surface infections like impetigo. Oral antibiotics for cellulitis or deeper infections.
  • Incision and drainage (I&D): For abscesses, your provider may perform a simple in-office procedure to remove pus and relieve pressure.
  • Wound care: Cleaning the area with mild soap and water, applying sterile dressings, and keeping the wound covered are key to recovery.
  • Pain and swelling control: Over-the-counter pain relievers like acetaminophen or ibuprofen may be used for comfort.
  • Follow-up visits: Recommended for abscesses or severe infections to ensure the infection is fully resolved.

Your provider will also share prevention strategies, such as practicing good hygiene, keeping cuts clean, and avoiding shared towels or razors to prevent bacterial spread.


Long-Term Outlook

With prompt medical care, most skin infections heal within 7–10 days. Deeper infections, such as cellulitis or large abscesses, may require longer treatment and close follow-up to prevent recurrence or complications.

At The Medical Group of New Jersey, our urgent care specialists provide fast, expert evaluation and treatment for skin infections—helping you heal quickly, avoid scarring, and prevent the spread of infection to others.
