Hi, this could be cervical spondylosis, hypertension etc. Get yourself investigated for cervical spondylosis. Investigations like MRI are helpful in coming to diagnosis.
For symptomatic relief try hot compressions on neck, back of the head, topical counterirritants and mild pain killers like paracetamol,ibuprofen etc.
hi my dear. My case is kind of similar to what u have and it makes me feel anxious most of the times.
