At each level in your cervical spine such as C4-5, C5-6, etc, you have a neural foramen, there’s one on each side, this foramen is where the roots are for
the nerves that go to various parts of your upper extremity, like the shoulder, arm
and hand, etc. You have osteophytes or bone spurs that are compressing these nerve roots, bilaterally which means on both sides. This is what is causing your pain. You have this at 3 levels and on 1 side at C7-T1.
