I was told my CT scan was normal. Does that mean I didn’t have a concussion?

No. CT scans and conventional MRI are not sensitive to the diffuse axonal injury that causes mTBI. A normal scan is common in mTBI patients and does not rule out a concussion. If you have persistent vestibular or visual symptoms after your accident — dizziness, nausea, light or noise sensitivity, blurred vision — you should be evaluated by a neurologist or concussion specialist, not just an emergency room physician.
