Hope your GP assesses you well, refers you onwards if necessary and that you mend well and fast.
Get you bike assessed by a professional and if it's not a write-off, keep inspecting it for damage that only becomes apparent later.
Likewise with yourself, look out for injuries you didn't notice at first; it's likely your back is so sore you might not notice much else that hurts.
Document EVERYTHING. Nag the police.
Hope you get sorted and compensated well.
