How does dizziness and vomiting return?

Hello, I'm a doctor in tongji hospital. According to your above clinical symptoms, I want to make a preliminary consideration:

1, considering the possibility of your eye disease (it is recommended to go to the hospital to check out glaucoma)

2. Suddenly raising your head or lowering your head will make you dizzy (I hope you can specifically talk about whether dizziness is dizziness or sudden dizziness). These two situations are considered differently. Please specify and consider the possibility of insufficient cerebral blood supply.

3. Have a good rest. If the above symptoms appear after rest, you must go to the local regular hospital for a detailed examination. After all, you are still young.
