What i the difference between a herniated and bulging disc?

I am wondering if they meant ruptured discs instead of herniated. That would be one blown out whereas the other is got pressure on it that can lead to blowing out. They are caused by tight muscles in your back, i'm taking it that this is where they are and not the neck, where the muscles are pulling hard and long enough to cause them to fail. Freeing up your back muscles will get the pressure off the muscles to get the pressure off the discs to save them from failure and here's how to free up your back muscles to get that relief:

Back:

(do from a sitting position)

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 fairly straight as you do. When you reach your lap remain there for another 10 seconds, 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. When the discs are ruptured it takes away the cushion between your vertebrae so I'm not sure what kind of pain may be left when you are done with this if that is what your dr. did mean. Wish they kept their jargon the same so there wouldn't be the guess work.

Actually none. Both terms are used interchangeably.
