If you can LIE FACE DOWN [prone] try doing some
McKenzie EXTENSION EXERCISES
try 3 sets of 8-10 reps : 1st set go easy – push up until you feel the pain-discomfort. Then each rep-set push a little harder. Don't force it or that may cause more muscle spasm as the protective spasm tries to resist the movement. They are painful because you are pushing – nipping the disc forward into a better position – keep hips and glutes relaxed. Rest between sets….. if you CAN'T lie flat on your tummy [ prone ] ....
Then try lying over a PILLOW or several – this will take the pressure off the BULGING DISC and give some pain relief but also give the disc a chance to REDUCE – after 10-15-20mins then slide the pillows out and try the McKenzie EXTENSION EXERCISES…..

Some patients present with a LUMBAR SHIFT – in that they are LEANING to one side… normally this is a response to a large BULGING DISC to the SIDE and the body’s response is to lean AWAY from the PAIN – normally no leg pain – and our aim is to get you straightened up by doing SHIFT corrections or SIDE GLIDE @the WALL exercises….
Normally good side to the wall and try work your hip towards wall, gradual increments – don’t force it.
picture on the right shows a right sided shift - normally pain is on the left side and patient is uncontrollably leaning away from the pain. To correct : lean right side [non painful side ] onto a wall and gradually work the right hips towards the wall. If pain starts travelling down the leg stop and get medical advice.
