jingl this might sound odd, but with reference to:
I know a really skinny little lady who's got carpal tunnel syndrome. How can it be weight related? It's not in a weight bearing part is it?
It's not exactly weight related as such, it's just that sometimes losing weight can alleviate the symptoms.
When I first got it I weighed roughly 10 stone, even at my small height (5'2") it's not exactly overweight, but when I went down to approx 9 and a bit stone, the symptoms were much less.
I think that with CTS the symptoms can vary. I wasn't much troubled during the day, but would wake up in the night with tingling fingers that felt as if they has been replaced by a pound and a half of thick pork sausages!
