Hi there @swimbikerun. You've explained what you experience just fine. I understand and get what you're describing as I myself experience visual flares while driving. It can be weird stuff! It's appropriate that you mention your city is crazy busy with multilane highways. This is a good analogy of CSS and how the central nervous system has the ability to heighten sensors and allow for an overreactive experience with something as simple as driving.

I'm happy to know you have had your eyes examined and feel confident that you are not having actual vision problems. That is huge! When in doubt its always best to rule out acute issues with your doctors.

Feeling what you describe can be alarming and confusing. From my personal experience, being a graduate of Mayo Clinic's Pain Rehabilitation Center (PRC), I was able to really embrace CSS and learn how my body and its hypersensitivities were affecting me in numerous ways. Also, how to manage the plethora of sometimes odd and altering symptoms like your driving experience.

I believe you and I chatted in the past about PRC. Have you learned more about CSS or given consideration to attending the program? Last I recall, your Mayo doctors were encouraging you to do so. Any thoughts or plans?
