I have been aching all over every day and getting sharp pains in my knee, hip and back for quite a few months now and it has got worse in the past month whilst I have been taking progesterone only pills. I thought they might be the side effects of the pills but I did have some pains before taking it. I'm wondering whether this could be Fibromyalgia that has been brought on by my endometriosis and adenomyosis. I also have an underactive thyroid which I think could be linked as well. Has anyone had similar symptoms and been diagnosed with both Fibromyalgia and endo? What treatment did you take for it?
