Knee pain is a common condition that can be caused by both short-term and long-term problems.
Many short-term knee problems do not need any help from doctors and people can often help with their own recovery. Home remedies can also help with many of the long-term problems with knee pain.
Get off your feet and apply a cold compress or bag of ice to the knee. Frozen vegetables, such as peas, will also work if you have no ice handy. Wrap your knee with a compression bandage to prevent swelling, but not so tightly it cuts off circulation. While you're resting, keep your foot elevated.
