Knee Pain

By answering just a few questions, it's usually possible to sort out whether your knee pain could be due to something serious.

Along with your knee pain, do you have one or more of the following:

• fever

• redness over or around the knee

• marked swelling of the knee

• inability to use the knee (for example, is it impossible for you to bear weight?)

• a recent, significant injury to the knee such as a fall or a motor vehicle accident?

Yes, I have or had one or more of these.

No, I have had none of these.
