Are most of the symptoms in the upper body? - hands/arms /head?
any leg or low back issues?

[3 mm disk protrusion at c4-c5 minimally abuts cervical cord.]

You probably got some sort of side impact whiplash effect , plus the above disk issue that shows as abutting the cord.

If you can get expert PT - are they now doing any pain relieving modalities for you?
Like ultrasound, IF stim, low level laser, trigger point therapy, massage??
If they are not addressing the pain level first to reduce that, then they are not helping you...
seek out a better/more advanced PT.

Some chiropractors use these modalities , and you may benefit from expert adjustments.. also. look into information on - upper cervical adjusting c1c2..
Of course make sure they see your MRI results before any treatment..
