I have Lordosis of back spine, need second opinion?

Loss of lordosis of back spine

I have this problem since last 10 years but I don’t aware of it but last 15 days I have very bad back pain so visit doctor and he took x-ray and the x-ray show that I have loss of lordosis problem.
AND physiotherapist TELL ME THAT IT WILL NEVER RESTORE NATURAL CURVE OF SPINE. I have to live rest of my life with lordosis problem. So I want to know that is it possible to restore the natural curve of my spine. Or it will never get back to its original posture.
