several years ago, I had a pinched nerve in a cervical vertebrae...pain, couldn't turn my head, had one arm propped up on a pillow at night. I had ONE treatment...an injection of cortisone into the area to reduce irritation and swelling. (and the doctor SPECIFICALLY prescribed a pain medicine for it, and it DID help) (Hydrocodone(Vicodin) one of those you must be careful about, but good for 'some' things on a temporary basis)

I still have to be careful and not twist my neck too far (or stand on my head like I did for my 50th & 55th birthdays..*grin*)...but so far it is managable. Do check whether the calcium deposit is of a size & location that precludes a try at that before you let them operate.
