Thank you for your answers !

Insurance wants me to have 6 weeks neck physical therapy first, and then reevaluate the need for neck MRI. I started the PT ( even that I'm afraid to have it before they know what's really going on in the neck ). I don't have to have office visit until I finish the PT, but it's been 8 days since the MRI and the dr. is not calling me back, and even if I call she won't call back until she wants to ( this is not the first time ).
No, there was no injury , I just woke up one morning 2 months ago and the pain was there.
What kind a dr. I should see for this issue ? ( neurologist ordered my MRI , because I saw her for headaches / lightheadeness )
