Without the ability to examine and obtain a history, I can not tell you what the exact cause of the symptoms is. However I will try to provide you with some useful information.
A concerning cause of neck pain associated with headache is a dissection: a small tear in the blood vessels that travel up the neck to the brain. This can occur spontaneously in people with certain conditions that affect the blood vessels, after neck trauma, or after chiropractic manipulation of the neck. The pain is often but not always associated with some sort of neurologic deficit as a dissection can often lead to a stroke. A dissection is diagnosed with a specific type of MRI test (MRA with fat saturation) or an CT angiogram.
I highly suggest you have vessel imaging performed to rule out dissection.
Thank you for this opportunity to answer your questions, I hope you find the information I have provided useful, good luck.
