That may explain why fibromyalgia syndrome, or FMS, is more common in women. Another theory states that fibromyalgia is caused by biochemical changes in the body and may be related to hormonal changes or menopause.
Not that the XF was bad, in fact it was very good, but just starting to show its age. The new Jaguar XF shares the same familial face as the XE and, while handsome, isnât much different from before.
