I started growing breasts at age 7 or 8 and was not a bit overweight. I started my period at age 11. I had reached my full height of 5' 8" by age 12 and was fully matured with a womanly body. I also had severe growing pains as a youth. I don't think the DES has caused all fibromyalgia cases, I just think it has added many cases to it . I think it makes it easier for us to get it and other autoimmune diseases. I hope that makes sense. LOL! It is just so strange that fibro began being diagnosed at such large numbers in the generation of this drug. I do think it has a correlation. I am a member of a group of DES daughters and get their emails everyday in daily digest. They sound so much like many of us. I hope one day we will know more about the drug.
