I have really bad knee pain after running. It doesn't sound like runner's knee from what I've read about it. It doesn't hurt to touch. It kind of feels like my knees need to pop but they don't. The pain is worse in the mornings when I wake up and when I go down stairs. It started on Monday after running and I've walked 5 miles wednesday and today (friday) and that was ok but I attempted to lightly jog and that wasn't happening. It hurts too much. I've taken up to 800mg of Ibuprofen and it doesn't seem to do much. I have stretched and they feel much better after stretching but it doesn't last too long. Is there anything I can do to help it? Does anyone have any idea what it may be? I am a little overweight and I'm new to fairly new to running but I've been walking a while with no problems. I have good shoes. I stretch before, midway and after walking/running. I'd really like to get back to running ASAP. Any help would be appreciated. Thanks!
