As you have mentioned the back pain occurs while you get up from the bed.. what kind of mattress do you use and what is your posture like when sleeping..
If your mattress is soft, than you need to change it and than if your sleeping posture is that of side lying than that should also be changed..
Twisting, and jerking movements do aggravate the back pain..
Next Steps
Pls visit a physiotherapist for proper diagnosis and treatment
