Left Disc

Focal left posterolateral disc bulge at c5-6?
I had a CT Scan done some time ago, and don't understand it... and the GP wasn't clear.
Can anyone decipher the jargon please. As I don't understand what it all means.
CT SCAN CERVICAL SPINE - C4 TO T1
Clinical: Pain in left side of the neck and tenderness along C5 to C7.
Technique: Axial scans from C4 to T1.
Findings: There is a small focal left posterolateral disc bulge at C5-6 protruding into the inferior aspects of the left foramen. The left C6 nerve root however appears to exit satisfactorily through the superior aspects of the foramen. The right foramen is normal. There is no focal disc protrusion at the other levels of C4 5, C6-7 nor C7-T1. Calibre of the central canal and foramina are within normal limits. Normal facet joints.
CONCLUSION: Small left lateral disc bulge at C5-6 encroaching into the foramen but no definite impingement on the left C6 nerve roots.
I'm not a doctor, but I know the anatomy of the spine, so hopefully I can help clarify some terms!
Your spine is composed of cervical, thoracic, lumbar, and sacral vertebrae (from top to bottom). Your cervical vertebrae is basically your neck area and consists of 7 vertebrae (i.e. C1 - C7). If you can find a picture of a cervical vertebrae (but not the atlas [C1] or axis [C2] because these are too high up and look different) and follow along, then it's easier to understand:
Foramen: There are two major holes in cervical vertebrae. The science community likes to make funny words for things, so these holes (you should see 3) are called foramens. The large hole in the middle is called the vertebral foramen and the two smaller ones are your left and right transverse foramens. Foramens allow for the passage of veins, arteries and nerves to other parts of your body. (Note: The findings don't specify which foramen it is talking about. I would assume the transverse foramen, but again...I'm not a doctor. You'd have to talk to your doctor about that if you're curious)
Posterolateral: That means posterior (i.e. behind) and lateral (meaning outwards. i.e. your shoulders are more lateral than your neck). So you can infer that there's a disc bulge that is more behind and more left (outwards) than normal.
Inferior and superior: If you are looking at your vertebrae from the top, then you are seeing a superior view. Think of it as if your head was chopped off and a bird flew by and looked down...it would be seeing a superior view. Inferior means you are looking at the vertebrae from the bottom.
Facet joints: Facets are part of the vertebrae (should be just on either side of the vertebral foramen in your picture) that help join to other vertebrae. It's like lego. The facets of one vertebrae will fit perfectly with the facets of the vertebrae above and below it.
I hope that helped a little bit. Sorry if it confused you more!
