I couldn't go to restaurants for months. It sounded like garbled noise coming at me from every direction. So for months boyfriend and I picked up food and took it to local park to eat. Much easier for me.

In the car you hear - voice(s), traffic going by, and other things. Might put you into overload.

Walking bothered me for months. Each step seemed to bounce in my head. Created an unbelievable headache.

These things still bother me to a degree. Some days more than others.

If 10 minutes is causing those symptoms try 5. Find a level that doesn't aggravate symptoms and then, ever so slowly, try to increase the activity.
