Tests and diagnosis
By Mayo Clinic staffDuring the physical exam, your doctor will check for swelling and points of tenderness in your affected limb. The location and intensity of your pain can help determine the extent and nature of the damage. Your doctor might also move your joints and limbs into a variety of positions, to help pinpoint which ligament, tendon or muscle has been injured.
X-rays can help rule out a fracture or other bone injury as the source of the problem. Magnetic resonance imaging (MRI) also may be used to help diagnose the extent of the injury.
