Hi- I've never posted here before, but I appreciate all the good ideas you post. I'm trying to stop taking estrogen and natural progesterone after taking them many years. My moderately bad knees seem worse; I know that there are studies that show HRT helps arthritic knees. In addition, I feel stiffer and have more muscle pain (usually don't have much). Does anyone have any personal experience or know of any studies showing that HRT helps people with fibromyalgia. I might decide that taking HRT is the lesser of two evils.
