Cellulitis usually refers to inflammation caused by bacterial infection of deep tissues that contain more fibrous tissue, which usually separates the tissues into small compartments. Therefore, when bacterial infection occurs, the inflammation becomes septic and it is like a honeycomb with one inflammatory tissue inside. If these inflammations are to be treated, in addition to antibiotic treatment, the main thing is to give local incision and drainage. The incision for this cellulitis should be large, and the entire infected lesion must be opened completely to clear all the channels before the wound can be drained, and the wound will gradually close after the drainage is cleared.
