Hi
Welcome to the MedHelp forum!
Dizziness while driving can be from driving anxiety, claustrophobia of being in car, carbon mono-oxide leakage (get this checked at a mechanics), subluxation of C1-C2 vertebra (a MRI of this spine should be done). Sometimes it is due to fluid in the cochlear canals of the ear.
Do discuss this with your doctor and get yourself examined. Hope this helps. Please let me know if there is any thing else and do keep me posted. Take care!
Try using a cervical collar, it helps.
have you damaged your neck in any way,or tense
