Hello! Welcome and thank you for asking on HCM! I understand your concern and would explain that your symptoms seem to be related to an occipital neuralgia. It may be related to a cervical column disorder (like a slipped disk or just degenerative changes). The fact that this is a new headache, never experienced before, is concerning for a secondary headache. I recommend consulting with a neurologist for a careful physical examination for neurological signs, a cervical column x ray study and some lab blood tests (complete blood count, PCR, sedimentation rate). A brain CT scan may be necessary to exclude a possible lesion of the brain (although less possible because your pain is not typical of these disorders, which cause exacerbation of the pain, mainly in the morning). Meanwhile, I would recommend taking painkillers like acetaminophen or ibuprofen. Hope to have been helpful! Best wishes, Dr. Aida
