Addiction to cortisone was the subject of the 1956 motion picture, Bigger Than Life , produced by and starring James Mason . Though it was a box-office flop upon its initial release,  many modern critics hail it as a masterpiece and brilliant indictment of contemporary attitudes towards mental illness and addiction.  In 1963, Jean-Luc Godard named it one of the ten best American sound films ever made.  John F. Kennedy needed to regularly use corticosteroids such as cortisone as a treatment for Addison's disease . 
Most injections into the knee or a smaller joint, like that at the base of the thumb, are simple procedures that can be done in a doctor’s surgery. When performed by an experienced physician, the injection is only mildly uncomfortable.
First, the doctor cleans the skin in the area with an antiseptic. If the joint is puffy and filled with fluid, the doctor may insert a needle into the joint to withdraw the excess fluid and examine it. Removing the fluid rapidly relieves pain also because it reduces pressure in the joint and may speed-up healing. Next, the doctor uses a different needle to inject the corticosteroid into the joint.
Injecting a large joint, like the hip, is more complicated and may require imaging tests to help the doctor guide the needle into the joint. Experienced rheumatologists, orthopaedic surgeons, anaesthetists, and radiologists may inject the facet joints of the lower spine.
