Manifestations of skin infections include redness, swelling, heat, pain, dysfunction and systemic reactions. After skin infection occurs, the skin will become red due to local vasodilation; fluid and cellular components leak out, which will cause localized swelling; local congestion and metabolic exuberance will result in elevated skin temperature and fever; the exudation of inflammatory mediators will cause pain; and on top of that, it can further cause organ dysfunction. Infection of the skin may also cause abscesses, etc. If the localized inflammatory lesions are more severe, a more pronounced systemic reaction can also occur, such as fever, changes in white blood cell counts, increased heart rate, and elevated blood pressure. If the infection is more serious, the abscess may break down and finally develop into sepsis. If you feel unwell, please consult a doctor promptly.
