[29M] Concern about a persistent lump on back

What might be happening

Based on the information provided, the most likely causes of your symptoms could be:

• Sebaceous Cyst: These are common noncancerous cysts of the skin. Cysts are abnormalities in the body that may contain liquid or semiliquid material. Sebaceous cysts are mostly found on the face, neck, or torso. They are slow-growing and often painless. Some can become large enough to be uncomfortable or painful. Squeezing one can lead to a painful infection.

  • Treatment can involve surgical removal of the cyst if it is causing discomfort.

• Lipoma: A lipoma is a slow-growing, fatty lump that's most often situated between your skin and the underlying muscle layer. A lipoma isn't cancer and is usually harmless. A lipoma can feel doughy and usually isn't tender, moves easily with slight finger pressure.

  • Treatment generally isn't necessary unless the lipoma bothers you, is painful or is growing.

• Dermatofibroma: Dermatofibromas are harmless round, red-brownish skin growths that are most commonly found on the arms and legs. Dermatofibromas contains scar tissue and feel like hard lumps in the skin.

  • Treatment is often not necessary unless it is causing discomfort or you are not happy with its appearance.

• Skin Abscess: An abscess is a painful collection of pus, usually caused by a bacterial infection. Abscesses can develop anywhere on the body.

  • Treatment typically involves draining the pus and taking antibiotics if the infection is severe or persistent.

What you can do

You should seek medical attention to get a proper diagnosis. Your healthcare provider may want to perform a biopsy or other tests to rule out more serious conditions such as skin cancer.

In the meantime, here are some things you can do:

1. Do not squeeze or try to pop the lump. This can lead to an infection.
2. Keep the area clean and dry.
3. Over-the-counter pain relievers can help with discomfort.

What you should look out for

You should seek immediate medical attention if:

• The lump grows rapidly or changes in color or appearance.
• You experience severe pain.
• The lump bursts open and pus or blood drains out.
• You develop a fever or other signs of infection such as redness, warmth, or swelling around the lump.
