Thanks to everyone for your positive replies
I thought it would be helpful if I posted a photo of Alisons leg so you have some idea of how the RSD affects her (Though Alison will never forgive me for showing her unshaven legs to the world !!!)
I obviously do not have to point out which leg is affected by RSD
Unfortunately you cannot see the spasms which come every couple of minutes and last for a similar length of time,and cause her toes to twitch uncontrollably. I am hoping to take some video and post a link at some point as it may be useful to some of you to see what these look like and to understand my concerns

Thanks again
Andrea
