Thank you for posting your query at DoctorSpring.com
I have noted your symptoms and would like to reassure you that they are not suggestive of any serious disease.
A normal CAT scan has ruled out any brain haemorrhage, fracture, etc.
The cause of dizziness is a condition called as post-concussion or post-traumatic vertigo, and it needs only symptomatic treatment. You can take betahistine tablets to get relief from dizziness.
You can wait to see your primary care physician and there is no need to visit WER at this point in time.
I hope it helps.
