Can you share a few more details about
where in your neck it is, what the pain feels like, etc.? Soreness, shooting, stabbing, electrical, cracking, pinching? Is it at the base of your skull, on the sides, along the vertebrae, in the muscles?
Do you do any sort of physical therapy, chiropractic, yoga, acupuncture, or other treatment for your neck?
Severe pain is so scary and awful.
I hope one of us can help you get to the bottom of this.
