Hello,
Thank you for your query at DoctorSpring.com
I have a simple reply if you have chest pain the reason is spondyloarthritis with Chron's disease. Well the site of chest pain can be adjacent to sternum that is breast bone, this is called as costochondritis. you can have lower and lateral chest pain and pare spinal chest pain that is on the back of chest adjacent to vertebral column due to enthesitis.
Neck pain can be mix of cervical radicular pain and enthesial disorder due to spondyloarthritis.
Can you send me the mri pictures i will try to figure it out, once you do.
Awaiting your reply,
Regards.
