I started my exercise routine back up in June and recently started getting into walking/running around my neighborhood on my off days from lifting weights. Last week I pushed myself a little harder and now I have some slight pain that seems to be just below my kneecap. Periodically as I'm going down my stairs at home my leg feels like it might go out but doesn't. Everything that I've read says to limit strain on the effected leg and try to avoid stairs (which is not possible at all at work and/or home).
If this is runner's knee how long should this last and is there anything else that I can do to help with the healing process? My exercise routine has barbell squats 3X week and some of the other exercises also require me to be standing/kneeling/slight squat.
