I sympathize with you. I have had this twice and both times it took several weeks to get over it. I found my knee/leg felt particularly weak when I was getting up off the floor or rising from a kneeling or squat position. It didn't seem to bother me while cycling too much though. I'm not a big proponent of antiinflammatories but my physiotherapist recommended a course of anti-inflammatories (Advil) when the other treatment, namely ice, ultrasound, and reduced activity didn't work. Basically 2 pills taken 3 times per day for 5-6 days to reach the "therapeutic dose". By the end of the 6 days I had no problems whatsoever. The Advil cleared up the inflammation that didn't seem to subside simply by icing and reducing activity levels. Taking the occasional Advil didn't help at all. Be cautious, though, with the antiinflammatories as they can cause stomach problems.
