Hi Sue,
Yes! I do experience day's where I am relatively pain free and I find I can get so much done! Problem wth me is though I usually over do things and end up bringing back the pain BIG time! LOL
But yes, it helps me to stay sain, knowing that every now and again I get a glimpse and ataste of the past... beautiful relaxed pain free days (providing it wasn't "that" time of month *sigh*), so grab hold of those precious days and savour the freedom and ease they provide! ;-)
love & gentle hugs
