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

They are usually caused by a bacterial infection. The most common bacteria present is methicillin-resistant Staphylococcus aureus. Diagnosis of a skin abscess is usually made based on what it looks like and is confirmed by cutting it open. Ultrasound imaging may be useful in cases in which the diagnosis is not clear. In abscesses around the anus, computer tomography (CT) may be important to look for deeper infection.

Standard treatment for most skin or soft tissue abscesses is cutting it open and drainage while using antibiotics. Sucking out the pus with a needle is often not sufficient.

Skin abscesses are common and have become more common 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 went to the emergency department for an abscess. In Australia, around 13,000 people were hospitalized in 2008 with the condition.

○ Treatment
Treating abscesses with over-the-counter drugs is difficult in most cases. If symptoms such as fever and chills appear all over the body, 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, the possibility of 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
  • The black dot in the upper part 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.
