Stew, and everybody else, thanks for your comments. It appears that this is exactly what I have, although I didn't start this topic. I read several articles on
http://www.itbs.info and it fits me perfectly. This prompted me to contact a local sports medicine and orthopedic surgery doctor, and I have an appointment for this Tuesday. I thought it was some freak occurrence I should live with until I read these posts. Thanks guys.
