As I went through your MR report and correlate with your clinical symptoms it implies that you have degenerative change (that is age related)
As you have disk c5-6 and C6-7 that demonstrates disk protrusion,This is not harmful as long as it does not compress thecal sac
but in C6-7 there is significant disk protrusion that causes compression of thecal sac that results in the symptoms that you are feeling eg pain in the neck that travels down to right arm.
If the pain keeps on increasing and does not respond to conventional medication you should consult a spine surgeon
who can suggest you surgical intervention and that may alleviate the symptoms.
