An abscess under the arm (also known as an axillary abscess) is a painful and distressing condition that occurs when bacteria infect the sweat glands or hair follicles. The image above depicts a serious infection where multiple lesions have developed under the arm, forming pus-filled bumps and deep inflamed tissue. This condition is not only uncomfortable but can also lead to complications if not treated properly.
What Is an Axillary Abscess?
An axillary abscess is a localized collection of pus under the skin of the armpit area. It often results from bacterial infections, most commonly caused by Staphylococcus aureus or Streptococcus species. These bacteria invade through small cuts, ingrown hairs, or irritated follicles, causing the body’s immune system to react aggressively. This immune response leads to inflammation, pain, and the formation of pus as the body tries to fight off the infection.
In severe cases, such as the one shown, the abscess can enlarge, creating multiple pus heads and discolored, swollen areas. The inflamed tissue appears red or purple, with visible signs of pressure and tenderness. Some of the darker areas may indicate necrotic tissue — dead cells that need to be removed to allow proper healing.
Common Causes and Risk Factors
There are several reasons why underarm abscesses form, including:
-
Excessive sweating: The armpits are warm and moist, creating a perfect environment for bacterial growth.
-
Poor hygiene or friction: Tight clothing, shaving, and deodorant use can irritate the skin, allowing bacteria to enter.
-
Ingrown hairs: Shaving or waxing can cause hairs to curl back into the skin, leading to infection.
-
Blocked sweat glands: When sweat glands are blocked, trapped secretions can become infected.
-
Medical conditions: People with diabetes, obesity, or weakened immune systems are at higher risk.
-
Hidradenitis suppurativa: A chronic skin disease that causes recurring abscesses and scarring in areas like the armpits and groin.
Symptoms of an Underarm Abscess
Early symptoms can be subtle but quickly progress. They often include:
-
A small lump or tender bump under the arm
-
Redness, warmth, and pain around the area
-
Swelling that increases over time
-
Pus discharge or multiple pustules
-
Fever or fatigue in severe infections
In the case shown, the abscess has advanced to a critical stage. The swelling is prominent, with multiple black spots indicating possible infection spread and deep follicular blockage. The large pus-filled center points to an abscess that requires immediate drainage.
Treatment and Extraction Procedure
Severe abscesses must be treated by a medical professional. The most common and effective treatment is incision and drainage (I&D), performed under sterile conditions. The steps typically include:
-
Cleansing the area thoroughly with antiseptic to prevent further contamination.
-
Administering local anesthesia to numb the site and minimize pain.
-
Making a small incision to open the abscess and release the trapped pus.
-
Draining all infected material and cleaning the cavity.
-
Applying sterile dressings and possibly inserting a small drain if needed.
-
Prescribing antibiotics to prevent the infection from spreading or recurring.
After the procedure, the wound must be cleaned daily, and the dressing should be changed under hygienic conditions. Painkillers may be prescribed to help with soreness and inflammation.
Home Care and Recovery
Recovery depends on the severity of the infection and how well aftercare instructions are followed. Key steps include:
-
Keeping the wound clean and dry.
-
Avoiding deodorants or shaving in the area until fully healed.
-
Using prescribed topical or oral antibiotics.
-
Wearing loose-fitting, breathable clothing to prevent friction.
-
Maintaining overall hygiene and avoiding pressure on the affected arm.
Healing typically takes one to three weeks, but in more severe infections, scarring may occur. Patients are advised not to attempt squeezing or draining the abscess at home, as this can spread bacteria deeper into the tissue or bloodstream.
Prevention Tips
To prevent future abscess formation, it’s important to adopt healthy skincare habits:
-
Regularly wash the underarm area with gentle antibacterial soap.
-
Avoid using razors that cause nicks or irritation.
-
Disinfect shaving tools before and after use.
-
Manage excessive sweating by keeping the area dry.
-
Strengthen your immune system through a balanced diet and hydration.
For individuals prone to recurrent abscesses, dermatological consultation is essential. A doctor can evaluate whether there is an underlying condition such as hidradenitis suppurativa or chronic folliculitis.
When to See a Doctor
Seek immediate medical attention if you notice:
-
Rapidly increasing pain or swelling
-
Pus draining with a foul smell
-
Fever, chills, or fatigue
-
Spreading redness beyond the abscess area
Delaying treatment can lead to cellulitis, abscess rupture, or systemic infection (sepsis), which can become life-threatening.
Conclusion
An underarm abscess, especially one as severe as shown in the image, should never be ignored. It highlights the importance of recognizing early signs of infection, maintaining good hygiene, and seeking professional treatment. Proper medical care not only relieves pain and prevents complications but also helps restore healthy skin and confidence.
If you experience frequent or recurring abscesses, consult a healthcare professional to uncover the root cause and develop a personalized prevention plan.
