I totally hear you about symptoms bringing on the anxiety. I personally haven't had that experience with my legs, except when I was on the blood pressure med Procardia for preeclampsia after delivering my post-mirena baby. My feet turned red and hot, and the top of my scalp was numb. Wierdest feeling, and it freaked me out.
I like Curezone better myself since you can search back and find good info, whereas you can't with FB.
