lawr64, your description makes me think you have bone spurs. They are sharp little boney growths called osteophytes. They like to stab your nerves.
If you haven't yet, you could get a cervical MRI. Depending on the reading you might try injections they intend to reduce any inflammation and may provide enough space for exiting nerves to relieve pain. You might try radiofrequency ablation it severs the exiting nerve that carries pain signal to the brain. Last of all, you can have those offending osteophytes removed in a minimally invasive surgery. https://www.neurosurgeonsofnewjersey.com/blog/posterior-cervical-foraminotomy-a-treatment-option-for-bone-spurs/
You know, though. that arthritis simply means inflammation in the joint. You could be having inflammation from looking at the computer in a position that irritates the joint, or from adjacent muscle adhesions. Practitioners sometimes use the term to dismiss our concerns.
In bracing myself at the end of a fall last winter, I disjointed my thumbs. Chiropractics restores the positioning but even chirpractors dismiss the discomfort saying--you just have arthritis. At your age you should expect it. I've had to insist on the adjustment. Now, I no long have "arthritis." You'll find relief after you find out why you have arthritis. Bless your struggle
