Yes, I do that fairly regularly. Walking exercises a lot of muscles just to fight gravity and keep posture. Laying in bed also causes muscles to relax which isn't ideal when the back is out of line. Like, laying in bed "relaxing" meant essentially agony for my back while "exercising" by walking made the pain completely disappear. I can tell it's not a bad sprain so it'll be completely gone in two or three days but walking is an essential part of the healing process, I know from experience.
