Lay flat on your back near a wall. Put the a pillow under your bum and lower back. Put your legs straight in the air on the wall. Make sure your bum is pressed up against the wall and your back and head is completely flat. You can do this on the bed or on the floor. 3 seconds that pain is gone. And if you take Motrin with an 8oz glass of water before you do this you will be fine for the whole day.
