Abscesshttps://en.wikipedia.org/wiki/Abscess
Abscess is a collection of pus that has accumulated within body tissue. Signs and symptoms include redness, pain, warmth, and swelling. The swelling may feel fluid‑filled when pressed, and the area of redness often extends beyond the swollen area.

Abscesses are usually caused by a bacterial infection, most commonly methicillin‑resistant Staphylococcus aureus. Diagnosis of a skin abscess is typically clinical and is confirmed by incision and drainage. Ultrasound imaging can be helpful when the diagnosis is uncertain. In perianal abscesses, computed tomography (CT) may be needed to assess deeper infection.

Standard treatment for most skin or soft‑tissue abscesses is incision and drainage, often combined with antibiotics. Sucking out the pus with a needle is usually insufficient.

Skin abscesses are common and have become more frequent in recent years. Risk factors include intravenous drug use, with rates reported as high as 65 % among users. In 2005 in the United States, 3.2 million people visited the emergency department for an abscess. In Australia, about 13 000 people were hospitalized with the condition in 2008.

○ Treatment
Treating abscesses with over‑the‑counter medications is difficult in most cases. If symptoms such as fever and chills develop, please consult a doctor as soon as possible.

  • inflamed epidermal cyst. The black spot is connected with the underlying cyst.
  • In this case of cheek swelling, an epidermal cyst should also be considered.
  • A severe form of Abscess can leave a scar. Minimal erythema around the lesion indicates that the infection is in the state of resolution.
  • Abscess ― five days after incision and drainage
  • A black dot at the top of the boil suggests an epidermal cyst.

Acute bacterial skin and skin-structure infections are a common reason for seeking care at acute healthcare facilities, including emergency departments. Staphylococcus aureus is the most common organism associated with these infections, and the emergence of community-associated methicillin-resistant Staphylococcus aureus (MRSA) has represented a considerable challenge in their treatment.

According to the sensitivity to antibiotic drugs, S. aureus can be divided into methicillin-sensitive Staphylococcus aureus (MSSA) and methicillin-resistant Staphylococcus aureus (MRSA). In recent decades, due to the evolution of bacteria and the abuse of antibiotics, the drug resistance of S. aureus has gradually increased, the infection rate of MRSA has increased worldwide.
