Prednisone can work wonders if your stiffness and pain is the result of inflammation due arthritis, bursitis, or simply overworked muscles. Steroids can reduce the initial inflammation and swelling that results from a more serious muscle tear, as Lindor obviously suffered, but it will not cause the damaged muscle fibers to regenerate and heal. In most cases, steroids actually slow the healing process long-term. So Lindor may have receive a steroid for the initial pain and inflammation resulting from the injury, but after the first few days, he is more likely to take an NSAID (meloxicam, indomethacin, naprosyn or celebrex) for 3-10 days. However, even NSAIDs can slow the healing process over time. The main treatment regiment is time with immobilization (cast/walking boot), ice for swelling and inflammation, and elevation. Unfortunately, there is no magic bullet, the body essentially has to heal itself to the point that Lindor can start a physical therapy routine.
