Panicking here a little. We are on vacation and walking a lot. DS has developed knee pain. Guessing patellofemoral pain syndrome. Pain in front, buckling, slight swelling.... He has never had pain before today. He has appointment to WP. If staying off of it, icing and NSAIDS around the clock don't help by the time we get home will take him to dr for eval. What do we have to do as far as reporting and if he just needs some rest and possibly PT what will happen as far as his appointment? I know no one probably know for sure, just looking for comfort!
