In the process of wound healing, there is actually granulation, which refers to the growth of tissue in the area of the original defective tissue, and the initial stage is granulation. This granulation is caused by the proliferation of blood vessels, which is the first step in the process of tissue repair, on top of which the nerve and fibrous tissue structures continue to grow and constitute the normal tissue components of the body. Granulation is a good stage of tissue repair, but it should be treated in a targeted manner, for example, some wounds with more severe granulation are a pathological condition that requires a definitive judgment. If self-judgment is difficult, it is recommended that patients should seek medical help in the hospital for wound dressing changes, as some of the granulomatous growths require professional disposition to ensure complete wound healing.
