I got kicked in the ribs about 10 years ago, and after an X-ray it was determined that I had 4 or 5 hairline fractures. I also had a cracked sternum(hairline). Somedays not very frequently I get pains just like I had 10 years ago, and it sounds like the bones pop when i stretch sometimes. Usally I'll have limited range of motion on one side. Is this normal? Do these injuries ever fully heal?
