Have 0 pain but c5 to 7 c spinal fusion recommended due to mri, EMG?

I have had a very stiff neck on the left side for months , had PT etc.. for weeks. Nothing helped, had an MRI which showed the C discs 5 6 7 are bad , no spinal fluid in there , did the EMG and since was told surgery carpal tunnel on the left wrist is recommended. again , I have no issues with my hand, nor wrist. Then I asked so if I have the laminectomy, the stiffness in my neck will go away and was told no that’s muscular. But if I don’t have the laminectomy, the odds of me falling, I’m 77 , could really injure my spine, then I would have issues with balance and possible pain in my legs , arms , who knows. Now I’m scheduled for a bone density scan which Medicare won’t pay for and scheduled for a neck ct . I am seriously considering cancelling everything! Not out of anxiety, but just wondering is all this really necessary as the only pain I have is apparently the stiff neck muscular pain so I’ve scheduled a couple massages. And See if that helps..
