Sorry for late reply.
Burning and pain is almost always associated with nerve involvement. It might not be your neck, but could by your shoulder, or even in the arm itself.
So you should try some self care remedies until you see your doctor in next few days.
Do gentle massage with topical diclofenac sodium on back of neck,shoulder and upper arm.
And warm compresses can be tried.
You can try OTC capsaicin cream and Advil also.
Do neck stretching,shoulder movements on slow pace.
Avoid sleeping on affected site.
X-ray/MRI can be done for further evaluation.
Feel free for further queries. It's good to discuss rather than quit.
Your satisfaction is our goal.
