The inflammatory phase is the body's initial cleanup and defense response after injury, aiming to stop bleeding, prevent infection, and clear debris. It typically lasts up to five days. Early on, neutrophils arrive quickly to clear bacteria, followed by macrophages that phagocytose debris and release signals to recruit more repair cells. By about days 3–5, this phase winds down as the tissue shifts toward the proliferative phase. If inflammation extends beyond a week, it can indicate infection or chronic inflammation, which can impede healing. Shorter durations, like two days, don’t allow sufficient immune cleanup; a full week is usually beyond the peak inflammatory window and into repair processes; two weeks is well beyond acute inflammation and into longer-term remodeling.
