Get your injuries on camera. Some will disappear from view as others start showing.
You'll have parts letting you know they're sore that you never even knew you had. As the pain eases in one area another will make itself known.
Get down on paper what happenned, before & after hitting the door. Include the last thing you remember & the first thing you remember. Don't try filling in any blank spots. For the period between your last recollection and your first after the incident, try and work out how you may have ended up at the point of your first recollection. It will help in trying to work out a timescale. Keep this bit loosely worded, stating that you have simply tried to work out how you managed to end up where you did.
This isn't advice from a cyclists point of view, but one I've been asked many times over the years by various doctors/nurses in various A&E departments due to epilepsy. It may explain some of the marks & also give an indication of any head injury.
Keep a check on the eyes over the coming days..
Best of luck in getting things sorted, but get yourself sorted first & then worry about the bike.
