I Have Been Having Lower Back Pain And It Has

I have been having lower back pain and it has been increasingly getting worse over the last few months. I am an LPN and lift clients but I also work out to stay strong. The spot is very tender to the touch. I got a massage thinking it would help but it still hurts constantly especially when bending over. It seems to be stiff. I previously sprained my back (about 3 years ago) at least that is what the chiropractor said but I never went into a drs office.
