Wound healing and scarring with an abscess is a purulent infection during the wound healing process. The scarring is granulation tissue repairing the wound, and the abscess does not touch the nerves, so no pain is felt. Acute, diffuse, suppurative infections may occur in the subcutaneous, subfascial, interosseous, or deep cellular tissue. The causative bacteria are mostly Staphylococcus aureus, Streptococcus hemolyticus, and Escherichia coli. Taking S. aureus as an example, abscess for wound healing, S. aureus infection produces plasma coagulase, so that the infection site fibrinogen is converted to fibrin, and severe sepsis can occur. In the erythematous stage, you can use hot compresses, apply ichthyol ointment, iodine, etc.. The pus plug can also be removed with the tip of a needle or the tip of a small knife, and should not be squeezed. It can also be treated with oral antibiotics such as amoxicillin and cefaclor. If there are multiple pus spots that have broken down, surgical treatment with incision and drainage is needed. If the wound heals and abscesses appear, do not self-medicate. The absence of pain does not mean that it is not serious, and you need to seek medical attention as soon as possible to avoid worsening of the abscess.
