What causes large pus and blood filled lump on middle of the back?
A large pus and blood-filled lump on the middle of the back could indicate a number of different medical conditions. It's important to seek evaluation from a healthcare professional to determine the exact cause and receive appropriate treatment. Here are a few possible causes:
1. Boil (furuncle): A boil is a skin infection that forms when bacteria (usually Staphylococcus aureus) enter a hair follicle or oil gland. It appears as a red, tender bump that can grow in size and fill with pus and dead skin. Furuncles can occur anywhere on the body, including the back.
2. Abscess: An abscess is a collection of pus that forms in the body due to a bacterial infection. It can develop in various locations, including the back. Abscesses are often accompanied by swelling, pain, warmth, and redness.
3. Hidradenitis suppurativa (HS): HS is a chronic skin condition that affects the sweat glands, primarily in the armpits, groin, and buttocks. However, it can sometimes occur on the back as well. HS presents as recurrent boils or abscesses, which may connect and form tunnels under the skin.
4. Folliculitis: Folliculitis is an infection of the hair follicles. It typically occurs when the skin is damaged, allowing bacteria to enter and infect the follicles. Folliculitis can cause red, swollen, and itchy bumps, sometimes with pus or blood-filled centers.
5. Cellulitis: Cellulitis is a bacterial infection of the deep layers of the skin. It can spread quickly and may involve a large area of the back. Symptoms include redness, swelling, pain, warmth, and fever.
6. Pilonidal cyst: A pilonidal cyst is a small, fluid-filled sac that develops in the crease at the top of the buttocks. It can become infected and filled with pus and blood, leading to pain, swelling, and drainage.
7. Back acne: Severe acne on the back can sometimes lead to the development of large, painful cysts or nodules that may become filled with pus and blood.
Without proper evaluation and treatment, some of these conditions can become serious and require additional intervention. If you have a large pus and blood-filled lump on the middle of your back, it's best to consult a healthcare professional for a diagnosis and appropriate management.
