corticosteroids are not pain relievers. they reduce inflammation. when corticosteroids relieve pain it is because they have reduced inflammation. while the inflammation for which corticosteroids are given can recur corticosteroid injections can provide months to years of relief when used properly. these injections also can cure diseases (permanently resolve them) when the problem is tissue inflammation localized to a small area such as bursitis and tendonitis.
is a cortisone injection merely a pain reliever or temporary remedy?
