    Call Your Doctor About a Strain or Sprain If:

    • You can't move or bear weight on an injured joint; you may have a broken bone.
    • The bones in an injured joint don't seem to be aligned properly, in which case the ligaments that hold the joint together may be badly torn, requiring surgical repair.
    • An injured muscle doesn't move at all; the muscle may be torn completely through and require immediate medical attention.
    • You have repeated sprains or strains, indicating a chronic weakness that should be evaluated by a doctor
    • You have difficulty moving or walking after straining any back muscle
    • You have a fever, and the injured area is red and hot; you may have an infection.
