Thanks Ken, David and Healthgirl. It's horrible not having a name or a reason for our symptoms isn't it?. I'm starting to think that I might never know the cause but I do find that taking an antihistamine at night helps a little and I wake less often with less of the burning pain. I'm wondering if this means that the SFN is part of ab allergic response to something but haven't a clue what this would be - not environmental because my environment changes a lot just now and my diet is consistently healthy and relatively additive free.

I went into shock when my rheumatologist told me that I don't have a connective tissue disease now so can't blame Sjogrens or RA anymore. My thyroid is supposedly well medicated and I've had lots of other checks but nothjng flags up apart from raised to high inflammation levels. Hey ho. Mat
