I also had to chase up the RAF to send my medical documents to the local GP after I'd left. They never cover that sort of practical thing at resettlement briefs...
Several months after I'd left, I received rather an acrimonious note from the dental section, demanding to know why I'd missed some appointment they'd made for me. My reply involved a sex and travel suggestion.
When I finally signed up with a local fang-farrier, I asked whether they needed my documents from the RAF. "Don't bother, they'll take ages and won't be much use - we can do a quick assessment of our own, which will be more accurate", they advised. Which indeed they did.
