Dear Manjil Gupta,
This type of pain for sure indicates neuronal involvement. Does she also have numbness
in the involved area? Is the pain more at particular movements? Or it is more at rest or in some particular neck position? Please take her to a neurologist
before you take her for any investigation as clinical judgement by the neurologist will help identify the need of the tests. As of the description, it does not look life threatening, but what is causing that particular set of neurons get irritated and cause this pain needs clinical evaluation. Dizziness
might be part of it again. Do not worry and get back to me for any further query.
