I tripped over a concrete stop in a parking lot and fell a couple of weeks ago. I fell flat and hit the asphalt the full length of my body, with a nose injury the most urgent concern. It was taken care of at the local hospital emergency room. There didn t appear to be any other injuries, except for a skinned right knee discovered that night when getting ready for bed. Now the knee is painful below and above knee cap and swelling developing on tip of knee cap that gets bigger as the day wears on. It causes pain if I bend the knee past 90 degrees. I m in the process of cardio rehab and having difficulty using the recumbent bicycle and elliptical machines since my short legs require bending past 90 degrees. Walking doesn t cause as much pain but the leg feels weak. What can I do to lessen pain/swelling. I can t get an appointment with orthopedist until next Thursday. My email address is YYYY@YYYY
