Hi Heather, I have fibromyalgia too. As Lyn says its quite common to have both (unfortunately!!) and its hard to tell which is which.
Regarding the lifting legs problems, I have this too, but no idea of the cause of that.
You could as your rheumatologist when you see him/her next, they will check for the tender points. An overlap is quite common too, and thats why its hard to differentiate. The hip pain again can just be tendon problems etc. Apparantly I have something called a trachanter bursa and need physio.
I hope you feel better soon.
