I'd avoid a gp if you aren't seeing one regualrly, cause you'll only end up with grief over the whole thing. I'd see an IM or a chiro. They are less likely to give you a hard time about your choice.
It may be true that DOCS becomes involved if you present at the hospital, but if it is anything like the involvement I had with them when DD3 was 3 months (unrelated incident) it is nothing to fret about. They visited once a fortnight, asked me my version of events 20 times, and then closed the case.
