ELI5: If inflammation is supposed to help the healing process, why does inflammation sometimes stay longer and not heal the damaged area?

Sometimes your body can get a bit overzealous about it’s defense (see: allergic reactions and autoimmune disorders) and your immune system will kill healthy cells in its quest to keep you safe. Injured cells release chemicals that cause inflammation, summoning more immune cells, creating a feedback loop. Eventually things calm down though.
