I have not been able to drive for the last 3 weeks. It all started when I was driving with my husband in the car, and all of a sudden I felt like I was going to faint. I pulled over on the highway. My heart was beating really hard and I was sweating. I am not sure though, if this was a cause or a result of me having to pull over. Ever since then, I have not been able to drive because every time I get in the car I feel out of it, I am lightheaded and about to faint. I feel this way when I am a passenger in the car. My husband and I don't usually have to go on the highway, but we did today, and the speed of the highway made my symptoms get a lot more exaggerated. The best way I can describe the feeling is that it felt like I was on a rollercoaster with no seatbelt and no sides on the car. Like the car was going to fly off the road at any second. I went to the ER the 2nd time this happened when I was driving and they did tons of tests..EKG, pregnancy test, CT scan, chest x-rays, and found nothing. I made an appt with my primary care physician and she thought it might be panic attacks. I have been on Zoloft for 2 weeks and seen no improvement. I started thinking they probably weren't panic attacks because this sensation occurs every time I am in a car, from the time the car is moving, to the time it stops. I made an appt with an ENT to get tested for Vertigo, although I have never heard of someone getting vertigo only when they are driving. If anyone has ANY ideas, please let me know because I am desperate for help. It is very frustrating not being able to drive
