 Lower back pain and VERY tight Quadratus Lumborum every morning, especially on one side
				Hello! I've had this issue for nearly 8 years now but no one has been able to help.
Issue:
- The longer I sleep, the tighter my QL gets (especially right QL) which causes low back pain. Soft mattress makes it worse (I sleep on a hard mattress now)
Background:
- Did Tae Kwon Do for years, until around 9 years ago. Lots of kicking, predominantly planting with my left leg and kicking with my right (may be a cause?).
- I have low grade spondylolisthesis but I don't necessarily think it's related (no back pain post injury for a year or two)
- I think I have weak gluteus muscles (i'm prone to developing ITB when I run, glutes don't activate properly, I have to make conscious effort to activate) OR they aren't weak, but are not activating properly (I can hip thrust 135 lbs)
What helps a little
- Leg workouts, particularly hamstring, seems to help a day or two after the workout
- I have not been consistent in training glutes but glute workouts dont show immediate relief
- Using a quadballer (like a foam roller but it's a wheel that can really dig deep) on my QL offers relief but doesnt fix the root cause
What makes it worse
- Deadlifts (which I don't do anymore)
- Hyper extensions (reverse hyper extensions don't bother me at all though)
Any help is appreciated

							I suggest you to try changing your mattress from hard to a soft one.
I also had been suffering from lower back pain for a couple of months.
But after getting rid of my older mattress and changed it to a new Nest Bedding Coupons mattress surprisingly my pain got all healed.
 
			
			 
							I suggest you to buy the best mattress for back pain. I was also suffering from back pain. Then I purchase a back supportive mattress from Refresh mattress. I feel better now. You can also take it from Refresh.
 
			
			 
							I think you are sleeping on a too firm matras.
It works the opposite. When muscles are able to relax they start to hurt.
Probably you are sleeping on a hard matras very long.
Then switching to softer make your muscles hurt temporary
