You don't need a CT if you are of child bearing age. The radiation is excessive and unnecessary. If there are no broken ribs you have cartilidge damage. I don't know what needs to be done to "assess" the site. If a physician does ask you to get one, he will have good reason.
The good news is that these injuries usually heal by themselves, but they take a long, long time.
Last august I fell and managed to break a rib or two. Black and blue city. The pain is just now disappearing.
If the cartilige is injured it too, takes a long time, if ever to heal.
You need to find a clinic, which will usually treat for $10 U.S. a visit, if you have no insurance or money.
Other than that you can look on the internet for what are called "Hill-Burton Hospitals", and visit one of those.
There is a possibility you have a ruptured spleen and should be seen in an emergency room. That is the main thing that strikes me as being a problem. Death is forever. That's the nice thing about it. There are also not-so-nice things. You don't get to enjioy sunsets and holding babies and telling people "I love you". Stuff like that.
Rather than make a presentation that "I need a CT", you need to go to a teaching hospital ER, as of an hour ago, present your symptoms, and don't worry about the bill. They will treat you without asking for up front money.
I am not a happy camper with your loving chiropracter. He is above his pay grade. You needed an evaluation at an ER by an M.D.
NO, your situation is NOT NORMAL. Well, hate to tell you, I think you need a CT vs a plain flat plate xray to reassess the site; CT imaging is better, but I know you didn't want to hear that. This is not something you will be able to "HOME REMEDY." I don't know how you will get out of paying for this one unfortunately. :(
