Dealing with lumps or bumps under the skin can be concerning, especially when you're unsure whether it's an abscess or a cyst. While both may look similar, they are different in nature and require different approaches to treatment. This article will help you understand what abscesses and cysts are, their symptoms, causes, and how to manage them effectively.
What Is an Abscess?
An abscess is a pocket of pus caused by a bacterial infection. It forms when the body tries to fight off an infection by sending white blood cells to the affected area, leading to swelling, pain, and redness. Abscesses can occur anywhere in the body, including the skin, teeth, or internal organs.
Symptoms of an Abscess
- A swollen, red, and painful lump
- Warmth around the affected area
- Pus or fluid discharge
- Fever (if the infection spreads)
Common Causes
- Bacterial infections (often Staphylococcus aureus)
- Blocked sweat glands or hair follicles
- Injuries that break the skin
What Is a Cyst?
A cyst is a sac-like pocket filled with fluid, air, or other substances. Unlike abscesses, cysts are usually non-infectious and grow slowly. They can develop anywhere on the body, including the skin, ovaries, or kidneys.
Symptoms of a Cyst
- A round, movable lump under the skin
- Usually painless unless infected or inflamed
- May grow slowly over time
Common Causes
- Blocked ducts or glands
- Genetic conditions (like polycystic kidney disease)
- Chronic inflammation

How Are Abscesses and Cysts Treated?
Treating an Abscess
- Medical Drainage – A doctor may need to drain the pus to relieve pain and prevent infection spread.
- Antibiotics – If the infection is severe, oral or topical antibiotics may be prescribed.
- Warm Compress – Applying a warm cloth can help reduce swelling and encourage drainage.
Treating a Cyst
- Observation – Small, painless cysts may not need treatment.
- Drainage or Removal – If a cyst becomes large or bothersome, a doctor can drain or surgically remove it.
- Steroid Injections – Used to reduce inflammation in some cases.
When to See a Doctor
Consult a healthcare provider if:
- The lump is painful, growing, or red.
- You develop a fever (sign of infection).
- The abscess or cyst keeps coming back.
