Sorry about that knee thing, Jean. Let us know how it's doing. It seems like everyone is being plagued by weird things... after a month of x rays, CT scans, etc. my doctor agreed that the weird pain in my back is muscular, probably from when i rode to work with a backpack about 8 weeks ago. I had pain and numbness then, but about 2 weeks after that, this pain started. Her prescription was muscle relaxants at bedtime and go get a massage! I am happily obliging her this afternoon.
