I'm sorry to read that you are still struggling with pain, @Cathyjbeck.
Have you tried cutting back on activities as the other staff members suggested? The fact that your "knee pain gets worse as the day goes along" is probably as sign that you are overdoing it.
I know it's frustrating, but try to be patient. You can't rush this recovery. It. just. takes. time.
