I am suffering from severe back pain since last two weeks and I am having Nucoxia 120 for relieving the pain.

Question

The pains are causecd by muscles being pinched in your back. To get rid of the pain you have to release the back muscles to free them back up and here's how to do that release: 
Back: 
(do while sitting on a chair) 
Place your left hand on your left leg next to your body. Place your right hand over your left shoulder, fingers over the back and the palm in the front, and firmly pull down on them and hold. After 30 seconds slowly lower your body forward and to the outside of your left leg, keeping your left arm as straight as possible. When you reach your lap remain there for another 10 seconds, then release the pressure but rest there for another 30 seconds. Then reverse your hand positions and do your right side. 
For best results relax your body first by taking a deep breath and exhaling then remain this relaxed.
