Girija, welcome to the board!
I�ve had the joy of dealing with trigger points, and the onset is still a bit of a mystery. I created a helpful FAQ on what they are all about, including treatment. BTW, if you don�t have the Trigger Point workbook, it�s a must read, see

I�ve read some research that hormone levels can be related to many (if not all symptoms) of fibromyalgia. Check out this article:
A randomized, double-blind, placebo-controlled study of growth hormone in the treatment of fibromyalgia.
