In patients with viral meningitis, there is often no significant change in cranial pressure in mild cases, and the patient may only show dizziness, headache, nausea, etc., which are not very serious symptoms. However, in severe cases, it does not heal on its own, so if you suspect that you have viral meningitis or have headache and fever, it is advisable to enter the hospital as soon as possible for diagnosis and, if necessary, for systematic treatment of viral meningitis.
