Had X-ray of chest. Chest is fine but spine showed "mild arthritis! " im only 32! have untreated anxiety n now terrified over this. What will happen?

Incidental finding. Sometimes when a doctor orders a test looking to make sure there is no lung problem for instance, the radiologist notices something on the x-ray that is completely unrelated to the reason the test was done in the first place. We call that an "incidental finding". If it wasn't a problem for you in the first place, try not to worry about it.
Probably nothing, . Best thing to do is exercise ona regular basis and keep in shape. You might consider a trial off milk(intolerance often associated with inflammation_arthritis a common form of inflammation)-also might help with anxiety symptoms.
