    Knee Problems and Injuries - Check Your Symptoms

    Call 911 if a bone is poking through the skin.

    Call a doctor if:

    • The hurt limb or joint looks odd, is a strange shape, or is out of its normal position.
    • The skin over the site of an injury is broken.
    • You have signs of nerve or blood vessel damage, such as:
      • Numbness, tingling, or a pins-and-needles feeling.
      • Skin that is pale, white, or blue, or feels colder than the skin on the limb that is not hurt.
      • Not being able to move the limb normally because of weakness, not just pain.
    • You cannot put weight on or straighten a hurt limb, or a joint wobbles or feels unstable.
    • You have severe pain.
    • You have a lot of swelling within 30 minutes of the injury.
    • Swelling and pain do not improve after 2 days of home treatment.
    • You have signs of infection after an injury. These may include increased pain, swelling, warmth, and redness; red streaks leading from the area; and fever.
