First of all, do I have cerebral thrombosis? Many patients suspect that they have thrombosis once their fingertips are numb, or their arms, legs and toe tips are numb, or they have pain in the strings, so they go to the hospital and ask for CT or MRI, but nothing comes out. We agree that patients are very concerned about their own body, but they should also have some medical knowledge, that is, if patients with cerebral thrombosis have numbness in the limbs, often the whole arms and legs are numb, and some of them also have facial numbness, then they must go to the hospital in time. However, in clinical practice, such patients often come to the hospital only after a few days of delay at home. Secondly, do I have a tumor? At present, the incidence of tumor is very high worldwide, and unfortunately, we often encounter young patients with tumor in outpatient clinics, which is why doctors are always willing to prescribe tests to patients. However, tumor phobia is very widespread nowadays, and many patients have to suspect when they have a slight pain in their head or a little numbness in their hands. In fact, the growth of brain tumor needs a process, often slowly progressing with headache, accompanied by nausea, vomiting, discomfort at the back of neck, and often some other manifestations, such as impaired eye movement, crooked mouth, numbness and weakness of limbs and so on. I hope you can pay attention to this. Of course, these are only generalities, and we will gradually refine some explanations of the condition, so I hope we can communicate more in the future.
