Hello and thank you for your question.
I am sorry you are in so much pain. Rib fracture can cause excruciating pain. The problem is that there really isn't much that you can do. The most important thing to check is that your rib did not puncture your lung, however, that is a very rare complication usually accompanied by shortness of breath (I am sure your chiropractor would have mentioned something if that was the case as it is easily seen on the x-ray of the ribs).
Now, more to your question...there are really no specific position that will help you. Of course, try not to lay down on the side where your ribs are broken. You might find it easier to sleep in a reclining chair (if one is available). Having a body pillow may also help you. I would suggest that you take 2 extra-strength Tylenols along with Motrin 600 mg (3 tablets of the Motrin pills available over-the-counter, each is 200 mg) at bedtime. If that is not enough for pain control, you might give your doctor a call for a prescription for Vicodin, Darvocet or Tylenol #3 (if you are not opposed to narcotics - short term will not cause problems).
Also, there would not have been much difference in your treatment have you known right away that your ribs are broken.
