I suffer from a very frustrating--to say the least--and frequently excruciatingly painful "incurable," albeit it sometimes somewhat "managable," rheumatic disorder called "fibromyalgia." Although no one seems to know whether "disturbed sleep patterns" causes/contributes to the pain or the pain results in disturbed sleep patterns, research has proven that fibromyalgia-like symptoms/pain MAY BE INDUCED in healthy subjects when deprived of sleep!
For what it's worth... :-)
