Pins and needles

Looking back over my previous posts I talked a while ago about pins and needles (Feb 11 http://hspjourney.blogspot.com/2011/02/symptoms-update.html), and thought I'd have a look to see what else I could find.

Pins and needles is really called paraesthesia, although it would appear also to be spelt paresthesia on some web pages (wikipedia indicates that the former is the British English spelling) http://en.wikipedia.org/wiki/Paresthesia

There are various website which indicate that paraesthesia is a possible feature in uncomplicated/pure HSP - for example http://neuromuscular.wustl.edu/spinal/fsp.html. But, I don't seem to be able to find any referenced papers/studies describing this. Some sites describe it as affecting "below the knee", others in the "lower legs" whereas others just list the term generally without indicating where it might occur.

My main reason, however, for coming back to this issue was that I don't think I've been noticing the pins and needles as much in the last few months and wanted to note that issue here. It doesn't take much reading to find out that pins and needles can be caused by dehydration, lack of sleep, stress, etc. etc. so, perhaps it was one of those (or indeed something else) which caused that then and not really since.
