If your pain occurs when you run then it is most likely mechanical pain and not chemical pain (inflammation). Aleeve is an anti-inflammatory and that may be why it is not helping. Most likely your body's biomechanics are to blame for the pain you experience with running. A few things to consider: type and age of your running shoes, surfaces on which you are running, your form while running, your natural posture (do your feet turn in/out, do your knees push in/out, etc). While you may be able to change the mechanics on your own, it may be beneficial to see a physician and physical therapist who can assess your posture/gait/running and help solve the WHY and then help improve your mechanics so the pain does not continue.
