shoot, sorry to hear that.
I think the standard responce is:
Are you a a CTC member. If not, might be worth joining, then you can access their legal services. Although you can go straight to specialist lawyer - Bikeline is a name mentioned often I think.

You've reported to police, good. He should have (I think, does that apply to dooring?). If he doesn't, then he's even more in fault. You may have to badger the police about it - or you may not. Be prepared to do that if you want recompense or justice. Or let the lawyers do it.
Record your injuries, get doctor's opinion, photos of bruises etc, write down how you feel, now and while you are experiencing it.
I hope the police track him down, and that he is insured. I'm not always keen on sueing for huge compensation, but in this case, he bloody deserves it for not giving you his details.
And get well soon. Look after yourself. Adrenaline may mask effects at first, and shock set in later. While you're busy sorting things out, you may keep going, and then suddenly it'll all hit you, so to speak, when you stop and think about it. So be prepared, and do whatever makes you feel better - chocolate, glass of wine (unless that interferes with pain killers), hug from a good mate.
here, have this
