What you have to accept and it's very hard to do is that in most cases RSD is nobodys fault. For some reason our brain decides that the pain we feel is beyond what it can accept and it goes into I suppose overdrive burning it so deep it cannot recover and doesn't realise the cause of the pain has stopped. The level of acceptaable pain is different for each person, that is why in some cases the cause is something as minor as a sprained wrist or twisted ankle.
