RA...does your Body fight the steroids

Newly diagnosed with RA was given steroids to help bring inflammation down but the day after i started steroids and since my stiffness and pain got worse, felt i was running a temp and felt like id been run over by a truck…since starting them nothing has improved and feels very much like my body is fighting them. Anyone else had this experience? Cannot understand if dose is not high enough, if i wasnt at peak of inflammation or if they just don't work for me
