I've searched the boards and all responses are just suggestions about therapy or chiropractor. I have an appointment for 9/16 but my disc has really started to flare up over the past few days. I guess making it to almost 24 weeks without being in true pain from it is good and I should be happy right!? Anyway wondering if anyone has any stretches or exercises that work well. I should add that I'm on pelvic rest so nothing to heart rate elevating. I've been doing cat/cow but it's not helping anymore.                 
                             
        
Re: Herniated disc stretches
Also I would suggest using a pillow between your knees at night and avoid scrunching up into the fetal position because that can make your disc bulge further. The key is to avoid slouching your low back this includes when sitting on the couch or in your car.
Hope this helps! It is definitely a good idea to get examinated to make sure this is actually your issue.
