Why do steroids help no matter what problem i have?

They affect cells: Corticosteroids function by first binding a receptor inside cells. Virtually all cells in the body have this receptor which controls development, metabolism, and immunity. Various health conditions may improve with systemic steroids because its effects are so widespread, but long-term use and high doses cause significant side effects. Steroids should therefore be prescribed and used judiciously.

Reduced inflammation: Corticosteroids, like cortisone, bind to the steroid receptor inside the cells. This causes the activated steroid receptor to block the formation of chemicals that promote inflammatory immune system reactions. Therefore, steroids help with the inflammatory reaction in any disease process that includes inflammation. This can range from rheumatoid arthritis, to asthma, to sunburn.
