Stretching for Back Pain
This worked very well for me really. Reduced the pain to about half, which is enough to at least allow you to function.
Pretty much I was just arching my back backwards. I don't think it matters whether you do it lying on your front and using your arms, or standing up and arching backwards by pushing your butt with your hands or something.
I was told it's good to do this 4-5 times for 20-30 seconds per time. Seems to work well!
It will hurt a bit at first of course and I don't think there's any need to overdo it. You wouldn't want to hurt yourself either so go easy. But yeah it was a bit of a lifesaver for me to be honest.
Stretching
★★★★☆
I did the following stretch and exercise and truly increased me flexibility in order to touch my foot toes. The best thing is that if I sit on a chair for a long hour and then I stand up I feel my back annoying me and cannot fully stand up. By doing the following for 6 minutes it relieves my back almost completely. Maybe it also helps at an acute instance of back pain.
