Hi TylerSmileR:
Welcome to the Squirrel Board and what is the name of your Squirrel!
I do not live in Oregon. There are many members on The Squirrel Board and hopefully someone will have the information you seek and will post this soon. I have some cautions and concerns for you below. Please read them and heed the warnings! There is no exaggeration in what I have written!
I did a bit of research and it appears that it is illegal to own a Squirrel in Oregon. You knew this but interestingly this was not so until 2017 and IF you had owned the Squirrel before that your ownership could be "grandfathered" and could get a permit. Again, going by the most detailed and one of the most reputable sources I have found, there is no other way to own a Squirrel and no permits are available unless you meet the requirements for being "grandfathered" you are a Rehabber! This is link is to a summary of this:

The Fish and Wildlife Department may very well say anything or even do anything to get possession of the Squirrel. They are NOT your friends when it comes to ownership of wildlife and do NOT care one bit about your Squirrel or you for that matter! Hopefully you did not give them your name or address. If they call, please give them no further information and tell them that you were calling for a friend whose phone is on the blink and you just wanted to get information about a permit for Squirrels for your friend but he is no longer interested and thanks for calling. IF you have already told them you have a Squirrel, tell them you let it go and do not give them any further information. Hopefully this will blow over! Also, to search inside your home will requires a search warrant but the Fish and Game people will tell you anything. Many Veterinarians, so-call nature reserves or even rehabbers especially in illegal States will keep your Squirrel and make it seem that the Squirrel will be cared for and cared about but virtually all of these confiscated Squirrels will be euthanized! If you care about your Squirrel and want to keep him, Do NOT give up your Squirrel to anyone and do not take your Squirrel anywhere unless you thorough vet the facility and never give your identifying information! Again, while this may seem paranoid, what I have told you is no exaggeration. Confiscations of wildlife by individuals and facilities that would seem to us as being friendly to you and your Squirrel occur all to often. We usually hear about it when it has already happened and believe me, in that case there is no getting the Squirrel back!
As to your comments about the injury your Squirrel sustained today, can you be a little more specific as to the details such what part of the head was caught and was the door slammed or just closed. Are there any wounds or swelling. Does he have full motion of his head and extremities and does it seem that both eyes are focusing and tracking. Basically, anything and everything that might pertain!
What has been your Squirrels diet? What makes you concerned about the possibility of your Squirrel having had inadequate Calcium intake? If there is concern about possible Metabolic Bone Disease (MBD) from inadequate Calcium I would recommend beginning the MBD Emergency Protocol from Henry's immediately! It is very simple to accomplish and if your Squirrel does not have MBD it is harmless and if he does it could very well be life-saving. Also you mentioned that you had an appointment with a Vet on the 14th. Have you vetted the Vet? Is the Vet Squirrel friendly and will they let you be with the Squirrel while there and will they give your Squirrel back to you?
Ibuprofen is ordinarily safe for Squirrels on a short term basis. An admin will need to review your Squirrels situation and if they feel that Ibuprofen may be helpful, they send dosing instructions to you by Private Message. Please obtain an accurate weight of your Squirrel preferably in Grams as this will form the basis of the dosing plan.
Regards,
