LUMBOSACRAL sPAiNe

Just got doc x-ray/ report on what's troubling my lower-right back. Report says :
LUMBOSACRAL SPINE:
There is straightening of the lumbar spine.
The vertebral heights and intervertebral disc spaces are maintained.
There is mild levoscoliosis of the lumbar spine.
There are osteophytes in the margin of the lumbar vertebrae.
There is no evidence of fractures or bone destruction.
The sacroiliac joints are unremarkable.
IMPRESSION:
MILD LEVOSCOLIOSIS WITH STRAIGHTENING AND SPONDYLOSIS OF THE LUMBAR SPINE.
And my doctor says it is NOT SERIOUS?!

What must I do now?
