Patient: Description of condition (onset, main symptoms, hospital visited, etc.): Patient female. 44 years old. Had headache before. But this time it was really bad. The pain has not improved for more than 10 days. Also semi-nausea. There is a lack of blood supply to the head; the CT did not detect the disease. The medicine I was prescribed did not help. I would like to ask you to take a look at the pain department of Jilin University Sino-Japanese Friendship Hospital: Hello! Because the condition you describe is too simple, I can not make an accurate judgment on your condition! However, some reference opinions can be published for your reference. In terms of the clinical manifestation of headache and nausea, there can be many causes, which need to be investigated one by one. Luo Min, Department of Pain, China-Japan Friendship Hospital, Jilin University I. Intracranial infections can cause headache and nausea, such as meningitis, brain abscess, etc.; II. Intracranial occupying lesions, such as pituitary tumor, meningioma, glioma, etc.; III. Intracranial vascular diseases, such as cerebral hemangioma, cerebrovascular malformation, cerebral infarction, etc.; IV. Eye diseases, such as glaucoma, refractive error (astigmatism), etc.; V. Extracranial infections, such as maxillary sinusitis, frontal sinusitis, etc. ; six, cranial neuropathy, such as trigeminal neuralgia, etc.; seven, the most common and most frequent disease: cervical spondylosis. Many of the above causes can cause the headache and nausea you mentioned. To determine which cause, it is necessary to present relevant clinical and laboratory tests after a careful physical examination, and finally make a clear diagnosis. If intracranial infection is suspected, a lumbar puncture and routine cerebrospinal fluid and biochemical tests are needed to make a diagnosis. If intracranial occupying lesions (brain tumors) are suspected, head CT, head MRI and, if necessary, enhancement examinations are required to make a judgment. If intracranial vascular malformation is suspected, cerebral angiography must be performed to clarify the location and nature of the lesion, make the appropriate diagnosis and determine the principle of treatment. If it is an eye disease, a clear diagnosis can be made with an ophthalmologic specialist examination, and it is easily cured. If maxillary sinusitis and frontal sinusitis are suspected, the problem can be solved by CT examination of the corresponding areas. As for cervical spondylosis, it is a common disease among middle-aged people. In the past, because people did not have good treatment methods, they could only carry out symptomatic treatment, such as injection, medicine, physical therapy and massage, but none of them could fundamentally change the course of the disease, which eventually led to recurrent cerebral infarction and cortical atherosclerotic encephalopathy (brain atrophy), which seriously affected the quality of life. After a series of extensive clinical exploration, we created a new treatment model for cervical spondylosis: the neuromodulation model. This has fundamentally changed the situation of cervical spondylosis that could not be cured for a long time in the past. If needed, you can come to our hospital for consultation.
