The knee is designed to absorb shock while providing a smooth, gliding surface through the articular cartilage. This alone makes it strong enough to handle the everyday stress that most people put on it. However, sudden injuries, such as a direct blow to the knee, or twisting, bending the knee or falling on them may cause bruising and swelling.
It can be just a simple pain that may keep you from performing your daily tasks, or it could be a constant pain that you may feel due to the presence of arthritis on the knee. Whatever the cause, knee pain must be addressed properly by professionals who offer different approaches to relieving pain.
