Hi Cathy...about four months ago I got pain in the middle of my butt. Then it went into my hip, down the side of my leg across my knee and sometimes it continures into my shin. It is mainly on my right side. I cannot pin point where the pain originates but it aches continuously and wakes me up at night. My thigh aches also and even clothes hurt against it. Don't know what it is, if it's just another fibro-thing or something else. All I know is that it HURTS!

Here is a link to the Arthritis Foundation. They talk about exercise and, at the right hand side of this site, they have range of motion and endurance exercise videos you can watch. This just might help you out. Here is the link.
I hope this helps you. I've had knee pain before and it isn't fun.
