Pull out Your Wallet
No, not just to buy something. Pull it out when you’re sitting, especially in the car. A wallet in your back pocket forces one hip to sit higher than the other. 
Uneven hips put strain on your low back, making it more likely that you’ll be seeking back pain relief again soon.
Sit Right
If you’re sitting at a computer, move your monitor up so that you’re looking straight ahead at the screen. Your elbows should be to your side at a 90 degree angle, and your feet should rest flat on the floor.
Positioning your body correctly, especially if you must maintain that position for a long period of time, can minimize muscle strain and help you to maintain correct alignment.
Fix Your Rear View Mirror
After your back adjustment, sit properly in your car and look at your rear view mirror. Position it so that you can see clearly. Then, the next time you get in, don’t adjust the mirror.
Adjust your body position. This will help you to maintain proper posture while driving.
