Could someone interpret my MRI results?

[FiregirlEm]

I have some sort of idea of what my results mean but if someone who knows how to read them could explain them to me better that would be great.
(I am a 21 year old female who is trying to figure out the cause of my Myoclonus a.k.a muscle jerks)
Thank you for any help.

CLINICAL HISTORY:Myoclonus.

TECHNIQUE: Using a 1.5 Tesla magnet, sagittal T1, sagittal T2, sagital STIR, and axial T2-weighted sequences of the cervical spine were preformed.

COMPARISON: None.

FINDINGS: The cervicomedullary junction is unremarkable.There is no signal alteration within the spinal cord.There is preservation of vertebral body height and alignment without evidence of signal alteration or acute abnormality.

At C2-C3, there is mild disc desiccation. No significant posterior disc abnormality, central spinal canal narrowing, or neural foraminal narrowing.

At C3-C4, there is mild disc desiccation. No significant posterior disc abnormality, central spinal canal narrowing, or neural foraminal narrowing.

At C4-C5, there is mild disc desiccation. There is slight and uncovertebral hypertrophy leading to mild neural foraminal narrowing on the right. The left neural foramen and central spinal canal are patent.

At C5-C6, there is slight disc desiccation. No significant posterior disc abnormality.There is mild right uncovertebral and facet hypertrophic change contributing to mild neural foraminal narrowing. The left neural foramen and central spinal canal are patent.

At C6-C7, there is no evidence of significant posterior disc abnormality, central spinal canal narrowing, or neural foraminal narrowing.

At C7-T1, there is no evidence of significant posterior disc abnormality, central spinal canal arrowing, or neural foraminal narrowing.

ln the remaining partially visualized thoracic spine, which are only imaged on the sagittal sequences, there is normal discs without central spinal canal narrowing.
The postcontrast images demonstrate no abnormal enhancement.

IMPRESSION:
1.No evidence of intramedullary lesion or abnormal  enhancement within the cervical spinal cord to suggest demyelinating disease.
2.Mild spondylosis of the cervical spine without evidence of significant central spinal canal narowing or disc herniation.
3. Mild right-sided neural foraminal narowing at C4-C5 and C5-C6.

Well, there is nothing remarkable there. No bone or disc presses on the spinal cord. No bone significantly presses on any nerve exiting the spinal cord though a "foramen" (window). No sign of demyelinating nerves, as in MS or other conditions. No sign of any tumor. The "mild" things probably don't matter at all.

One might then think to look for a problem in the brain.. EXCEPT that you get arm pain from having an MRI. So that seems to say that your nerves are possibly hyperexcitable. Hopefully you've told your neurologist about that.  

Were you exposed to some toxin in the period before your symptoms began?
