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 while raising up which happened last week. Now you feel dizzy and nauseated to the point where you have to stop the car and get out.
I feel you had sustained minor injury, I can say that as you didn't had any dizzy feeling,
vomiting and didn't loose consciousness when you injured your head.
Now for your dizzy feeling and nauseated while driving. As you mentioned you have this feeling while driving only, 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 is possibilities that you might have similar problem when you turn your head suddenly to one side. You can wait and watch if it comes down. If not you can try few exercises like
Epley maneuver, and similar one which you can find the internet. 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
