Knee pain associated with running is a common problem, and there are a few specific types of knee injury
that can be treated. Your primary care doctor
or a sports medicine doctor
should be able to help you with this.
Unfortunately, it is important to remember that running is not for everyone. It is a high impact form of exercise and, despite taking precautions, you may find that it remains uncomfortable and that you need to switch to a different form of aerobic exercise, such as swimming or elliptical.
Patello-femoral pain syndrome (runner's knee) is caused by the patellla (kneecap) tracking poorly over the femur (large leg bone). This causes pain over the top of the knee primarily. In addition to decreasing the amount of running you do, there are specific stretches and quadriceps strengthening exercises that can help, which you can find online or from a personal trainer.
Iliotibial band syndrome is the other major cause of knee pain with running, usually pain that is more located on the outer edge of the knee cap. This is an overuse injury to the iliotibial band, and it can be improved with stretches and strengthening of the opposing muscle groups.
