Ribs bent from repeated heavy recoil ?

[^v^Tinda wolf^v^]

I have a question for those who shoot heavy recoil guns regularly and that have had chest X-rays done. I just finished my physical exam with flying colours but on my lung X-ray it showed my top two ribs on my shooting shoulder bent in wards or kind of down some what. Has anyone else who have had X-rays done and regularly shoot heavy recoil guns noticed this ? I can't really explain what else would cause this ? I've never broken any bones or had any shoulder pain except for when I shoot a lot and even then so the pain is mangable and only lasts briefly. Maybe it's just my normal structure but if anyone else has noticed similar issues I'd like to hear about it. Thanks
