I can't say that i've got any problems with my car but noticed that it became uncomfortable to drive long distances, because of my back pain. My doc examined me a month ago, but he didn't reveal anything. He just prescribed me to pay several visits to my therapist, but i don't have a lot of free time,so i'm looking for some alternative way. I found some web it offers some back massages, i still have some doubts, but i'll probably try one. Does anyone have such device in their cars?
