Thanks Pete and Mike,
My hip and knee are a bit better

although my leg is still hyper extended although mum and James can now bend my hip 20 degrees and bend my knee to 80 degrees. They gave me 20mg rectal diazipam (which we normally use for storms or sedation and started physio. The leg is still shaking a lot of the time but not as badly so fingers crossed we've got it under control - it's just going to take a long time to get it back. Mum and James both feel that if my joints go into that sort of spasm that we have to get it out as soon as possible or it can become a permanent contracture.
Mike - I've had the trial for the baclofen pump as I take 100mg a day of baclofen. However, it didn't make a large enough difference for me to go through the surgery, especially considering how much pain I am in whenever I come round from a general anaesthetic.
Thanks
