HELP WITH RUNNER'S KNEE
How do you know you have it?
You will feel pain in the front of the knee or possibly hear popping either under the knee or on the sides of the knee.
If you kneel, walk down stairs, or do any activity that puts force on the knee, the symptoms will become more pronounced.
You might experience stiffness in the knee when sitting for a long period.
Some of the causes of Runner's Knee include:
Running on the same side of the road (due to the angle of the road),
Repeatedly using heavier than normal weights during weight training,
Muscles on the outside of the leg are stronger than those on the inside,
Leg is rotating inward.
What to do:

Reduce your running to 1/2.
Try crosstraining with any sport that does not put pressure on the knee (swimming, biking, inline skating, water running, or cross country skiing).
Ice the knee twice a day for about 15 minutes to reduce inflammation and pain.
For pain and swelling take ibuprofin or aspirin .
Try a knee brace while exercising.
If the pain is
TOO great to run, STOP completely and seek professional medical help.
To avoid the problem in the future:

Try wearing orthotics to correct foot mechanics.
If you constantly run on the same side of the road, when it's safe, try switching over to the other side and run with traffic.
Run on flat surfaces whenever possible.
Work on strengthening the quadricep, hamstring and calf muscles.
