Joint Pain And Inflammation
Most forms of joint pain involve some kind of inflammation — either local or systemic. When injured, a chain of events in your immune system known as the inflammatory cascade is triggered. In a careful balance of give and take, this process starts with pro-inflammatory hormones calling out for white blood cells to clean up damaged tissue and clear out infection. This is what causes the redness, swelling and pain we often see with injury.
Next, anti-inflammatory compounds take over to heal the area once the threat is diminished. When this process, known as local or acute inflammation, waxes and wanes in response to injury it’s a sign of a healthy immune system. Yet when the symptoms of inflammation don’t disappear, it tells us that your immune system is unable to turn itself off when it should.
Just as the flame of a burning fire can help or hurt, our body’s internal fire has the dual power to heal and to cause us pain. Think of inflammation like a burner on your gas stove; local injuries and infections cause our bodies to turn the flame up high in the area of the injury, while with systemic or chronic inflammation, our bodies keep the burner on simmer, even when we’re not suffering an injury. This slow burn has been associated with range of health conditions and degenerative diseases, including asthma, allergies, skin problems, insulin resistance, irritable bowel syndrome, heart disease, Alzheimer’s and yes, arthritis.
In terms of our joints, pain stemming from an injury or even short-term overuse can set off localized inflammation in the cartilage, tendons, or bursae. As the injury heals, players in your inflammatory cascade will perform their tasks and disappear. If the inflammation persists it can lead to a more chronic condition. Luckily, we now have a few tests that tell us a great deal.
