What is inflammation?
Inflammation is the body’s normal protective response to an injury. In inflammation, our white blood cells fight to protect us from infection, for example from bacteria or viruses. It can also occur when our bodies are injured. Inflammation is marked by an increased blood flow to the affected area. This allows white blood cells (neutrophils), and a host of other cells (basophils, monocytes and macrophages) to reach the area of inflammation.
Symptoms of inflammation
There are five signs, or symptoms, that may indicate an acute inflammation: redness, heat, swelling, pain and finding it hard to move the affected area of your body normally. Some inflammation may be minor, affecting only a small area and will heal on its own, but it can also be widespread, painful and require treatment.
How long does inflammation last?
Acute inflammation usually lasts for a few days and is normally beneficial for the healing process, though often accompanied by sensations such as itching or soreness (which may be unpleasant at times).
