The first step in the treatment of purulent dactylitis is to clarify the goal of treatment. The goal of treatment of purulent dactylitis is to protect the tactile sensation of the fingertips, that is, the sensation, to know the cold to know the heat to know the pain, to protect the sensation, including the abrasion resistance of the skin, because the fingertips are often in contact with objects and need to be abrasion resistant. When the infection is in the state of cellulitis, when it has not yet suppurated, the affected limb can be elevated, the application of antibiotics, including hot compresses, the treatment effect is better, and need to brake, braking a few days after the symptoms can be improved. If the effect of these treatments is not good, for example, if the symptoms last longer than 2 days, or if an abscess has formed and a fluctuating sensation is felt, it is necessary to make an incision and drainage in a timely manner. After the incision and drainage, the pus is drained out and the pressure inside the lesion is reduced, which can quickly relieve the pain and prevent the formation of osteomyelitis of the finger.
