Having a knee injury can be very painful, but it can also be hard to tell when it is necessary to go to a doctor or when it acceptable to stay home and rest it. Depending on your knee injury your pain can vary in the location and the severity of your knee pain. Some symptoms of knee pain is swelling and stiffness, redness and warmth to the touch, weakness or instability, and popping or crunching noises (Mayo Clinic, 2012).
