Occipital pain behind the head: firstly, exclude whether there is a history of trauma behind the head that causes occipital pain, if there is no history of trauma, exclude whether it is a cervical spine related disease that causes nerve irritation, resulting in occipital pain, such as patients with cervical spine osteophytes and cervical spine curvature straightening. Secondly, if there is no disease in the cervical spine, it is also necessary to consider whether it is caused by organic lesions in the posterior cranial fossa, and whether it is due to parasites, tumors, cerebral edema, cerebral hemorrhage, and other occupying lesions. It is also necessary to consider, whether it is caused by neurovascular diseases, or due to migraine, inflammation of occipital nerve, etc. If the symptoms persist and are difficult to reduce, relevant auxiliary examinations such as cranial CT, MRI, etc. need to be done in the hospital to confirm the diagnosis. If the occipital pain is only related to cold, its symptoms will be relieved with the cold and the symptoms will be reduced until they disappear.
