Break the Cycle of Chronic Inflammation
Most persistent pain from an injury is caused by a vicious cycle of inflammation
Cortisone is an analog to your body's naturally occurring glucocorticoids which are synthesized normally in the adrenal gland in response to pain and stress. If an injury results in severe inflammation and perpetuates a cycle deconditioning then occasionally the bodies natural response is overwhelmed.
Injection of cortisone into an area of chronic inflammation can help the body break the cycle of inflammation and restore the natural homeostasis of the joint or connective tissue.
Unlike oral steroids that need to be taken in high doses systemically and can cause a wide range of side-effects, injection of corticosteroids produces little systemic absorption and has very limited down side risks.
