I used to have severe muscle cramps like the ones you discribe especially while riding in the car. We had a Ford Taurus that was so uncomfortable for me I would have tears in my eyes if we were in the car for more than a half an hour. On long trips I would just sit and squirm. Miserable. Then we traded that car for another Taurus with power passenger seats What a difference a seat makes! We can go anywhere now. The seat can make a difference. [log in to unmask]
