When I was a teenager I had a severe migraine, for which the paramedics gave me a muscle relaxant. Once to the hospital the ER physician gave me more muscle relaxant, which stopped my heart. During CPR my xiphoid process was fractured. I had severe pain for the next 3-4 months. I can no longer feel my xiphoid process. In an unrelated medical process, I had an EKG done, which showed normal heart function. I have always had difficulty taking a deep breath since the CPR and occasionally have sharps pains right below rib level. My question is the following: Is it possible for a bone to be eventually absorbed by the body after it fractures completely? Or does it always "float in the body?"
