Thanks for replying everyone
I don't think the passing out is medication related
The only medication I was taking when all this started was ketamine because nothing else works for me and I have been taking ket for well over a year
I tend to think its just another problem associated to the RSD
When I was in GOSH a couple of years ago my therapist told me about a girl who used to pass out regularyl because of the pain so I guess thats what might be happening here
My consultant hasn't come accross it before and is going to look into it - he wasnt overly worried until it resulted in this back injury
Its now difficult to plan my life round it because I can't risk being out when the collapsing starts
