I heard that epidural leads to permanent back pain post delivery..is this true?

It depends on person to person. There are many of my friends who haven't taken epidural but still complain of back pain. And there is my SIL who took it but never had back pain because of this reason till date. Touchwood. I always used to hear that if you have C-Section then you will have lifelong back pain and many other things that does not happen in normal delivery. But (again Touchwood for myself), I am just fine. I think what all that depends is how your body system is, how ell you take care of yourself not only during before and after delivery but all through your life. And as far as back pain is associated with epidurals, I won't say that is all a lie but it also doesn't mean that you will surely have back issues if you go for epidural.
