Steroids are a man-made version of chemicals, known as hormones, that are made naturally in the human body. Steroids are designed to act like these hormones to reduce inflammation.
They’re also known as corticosteroids, and are different to anabolic steroids used by bodybuilders and athletes.
Steroids won’t cure your condition, but they’re very good at reducing inflammation and will ease symptoms such as swelling, pain and stiffness.
Usually inflammation is the body’s natural reaction to infection or bacteria. Your immune system produces extra fluid to fight infections or bacteria, which causes swelling, redness and heat in the affected area. You might have noticed this if you have had a cut or wound on your skin.
