"For years I had been a "junkie"--addicted to prescription and over the counter drugs. used oral and topical anti-inflammatory corticosteroids for 9 years to suppress my eczema/psoriasis. The steroids' side effect nearly killed me and did nothing to cure my eczema. Why elimination or suppression of the symptom is NOT the same as elimination of the disease . The side effects caused me to swell-up like a balloon and triggered terrible mood swings from deep depression to nasty outburst our rages. Functioning of vital organs such as my liver, kidneys, lungs and spleen were nearly shut down and I thought I would die." Shirley
One way that it works is to decrease inflammation (swelling). It does this by preventing infection- fighting white blood cells (polymorphonuclear leukocytes) from traveling to the area of swelling in your body. (This is why you are more prone to infection while taking steroids). Taking advantage of the anti-inflammatory properties of the medication, corticosteroids are used to decrease the swelling around tumors. For example, by decreasing swelling around tumors in the spine, brain, or bone, it can decrease the pressure of the tumor on nerve endings and relieve pain or other symptoms caused by the pressing tumor.
