Degenerative changes including uncovertebral joint changes in the cervical spine
are most commonly age related. These changes are nearly normal at older ages but may also occur in youngsters who have chronic neck strain
(common in soccer players, persons who work long hours on computer or hunched at a table).
Straightening of the cervical spine may occur with neck strain or after an injury
but does not usually signify any serious problem.
Left neural foraminal narrowing in this case also appears to represent age related degenerative change. If you are symptomatic, ie, there is tingling/numbness
of fingers of left hand, there is shooting pain radiating along the left arm or there is weakness of the left upper limb you may need to undergo an MRI of the cervical spine to assess nerve root compression
which then needs to be treated.
If you do not have any such symptoms, these findings maybe ignored and you do not have anything to worry about.
