Back breaking

For almost a month, I been enduring a long stiffness in my lower back. The aches are relatively light but the tightness bothers me.

I never bother to stretch prior to my gym training. However nowadays I would give a good stretching for 10 mins. Its important that I wont hurt myself after. Despite all this, the backache persist and its killing me.

Could someone heavy please step all over my back. It might just help undo the muscular problems.
