Disease analysis: Hello, granulation tissue is filled with granulation tissue at the injured site because of tissue defect, which contains new blood vessels, nerves and fibrous connective tissue. If there is infection, foreign body or poor blood supply in the injured part, unhealthy granulation may appear, the surface color is not rosy, there is no sign of bleeding when touching, and it is covered with annular necrotic tissue.
Suggestion: It is recommended to go to a hospital and ask a doctor to treat the wound. If there is infection, remove the infected tissue and scrape the surface with a blade until blood oozes slightly, which stimulates healthy granulation growth. I wish you a speedy recovery!
