The knots could be from Myofascial Pain Syndrome, a chronic pain disorder that is often associated with other conditions such as Fibromyalgia (and probably also Lupus).
Some info can be found at the following websites:
http://www.sover.net/~devstar/ http://www.emedicine.com/PMR/topic84.htm http://www.medicinenet.com/muscle_pain/article.htm The symptoms of Fibromyalgia include widespread pain for more than 3 months, and may also include Irritable Bowel Syndrome, fatigue, stomach upset, sinus congestion, allergies, food sensitivities, etc. The first link above gives lots of information about
Fibromyalgia as well as Myofascial Pain.
I hope this is helpful. Take care,
