Sorry to hear that Fluffy. write down all the details NOW, you'd be suprised how the memory fades without you realising it, and having a full detailed account, even of seemingly unimportant details will add to your credibility should it come to that.
Be aware that injuries can be worse than they initially seem, as they swell etc, especially complicated joints like wrists and shoulders, so don't rule anything out now. When I was run over I went back to work and finished my night shift (albeit in a lot of pain by the end of the night), in the end I got £3000 for the injuries.
Where was it by the way, what with me being a fellow Rochdalian?
Others have made recommendations about legal advice, but I can also recommend my friend who did my case, she's a legal rottweiller! PM me if you need to.
