pbob,

You are experiencing a common symptom of PCS. You have reached that threshold where you brain has become sensitive to movement. Many of us experience the same symptom.

We may struggle with shaking our head "no" or have problems riding in a car on a rough road.

Some will have a difficulty jogging due to the impact of the foot plants.

The only way we have learned to deal with this is to stop doing it.

No more head shaking. This will take some serious discipline. I've done it. I know how difficult it is.

Riding in a car on a rough road can be better tolerated if you sit forward with your shoulders away from the seat back.

A back that is rolled forward, especially at the shoulders will absorb far more vertical impact than a erect one. I use this shoulders forward posture to snow ski. Without it, I would never be able to tolerate the bumps om a ski run.

Good shoes help, especially if you do any running/jogging. A good way to sense the impacts of a foot plant is to try some foam ear plugs. This will magnify the impact to your brain. By changing your foot plant (the way your foot contacts the ground), you can reduce this impact. A good running foot plant might start with an outside heal contact with a push off from the big toe. Try different shoes.

The foam ear plugs should be with you ate all times. Then, when you unexpectedly encounter a noisy environment, you can put them in. The yellow cylindrical foam plugs work best. Avoid the ones with a string connecting them. The string conducts noise to the ear plug.

They can be easily reused. Turn on the bath sink faucet and let if get hot. Leave the plugs in the stream of the flow and it will tumble them. They will come clean. Or you can leave them in the pocket of a pair of pants. This works too. LOL

Hope this helps.

Don't be afraid to ask us about your struggles. Likely, many of us have already experienced the same thing.
