lwbarker, fractures are often not evident on early xrays. I would ask for an MRI, especially if the pain is increasing. Increasing could mean that a fracture is unstable or unable to reconnect. An MRI would also determine if there there is injury to the spine. If the rib is a simple fracture, there isn't much remedy. And there isn't much sense in knowing. They are painful and take some time to heal. If you were to take a bone building medication (like Forteo) it would heal more quickly. Many express pain relief when taking Forteo after a fracture.
If you roll to your side evenly when rising from supine it can be less painful.
Have you ever been diagnosed with osteoporosis.
