Hi there,
I am Dr. Deepak, I work in Emergency Department, where I see many patients with
injury to their head. As you mentioned you had injured your head as someone landed on you and you hit the floor. Since then you are having headache, severe
vertigo and
vomiting. You are not able to eat properly.
Your feeling of vertigo and vomiting is more, when you get up from the bed and when you turn your head to one side suddenly. Mostly it look like ear problem. Are you having any
cough,
cold or running nose? It can lead to ear block and cause similar problem. If not do you any problem with ear, like reduced hearing, ringing sound in any of the ear?
There are few small stones on both side of our ear, which help us balance. There is possibility that you might have displaced one of these stone from its place when your head hit the floor.
In my opinion you can
1. You can wait and watch if it comes down.
2. You can try few exercises like
Epley maneuver, and similar one which you can find the internet for the treatment of vertigo.
3. If it still persists then you can show it to an
ENT specialist. Who can examine you and let you know what might be the problem.
Thank you
Hope your concern was dealt with and hope you have a speedy recovery
