Knee discomfort isn't always harmless or easy to heal. If your knee discomfort travels to your foot, it may be nerve-related. Dr. Goldman suggests a neurology assessment.
Runner's knee, or patellofemoral pain syndrome, causes discomfort at the front of the knee and around the kneecap in the morning. Misaligned kneecaps don't rest in the femur's trochlear groove.
ITBS is related to runner's knee. While more prevalent during exercise, severe discomfort may sometimes occur overnight.
As we approach middle age, past traumas or hereditary predispositions cause knee cartilage deterioration. Cleveland Clinic calls this osteoarthritis.
A swelling knee that hurts when you walk on it or twist it might indicate a torn meniscus, Dr. Goldman adds.
The meniscus, cartilage that cushions your knee, is often damaged.
If your knee locks or buckles and you have difficulties holding your weight when you stand, it may be an indication of a torn ACL, according to the Mayo Clinic.
