Thanks for your question -
It is unlikely that a brazilian butt lift in the true sense of the definition will help your pain. There is a large chance that you will have the same pain post-operatively that you had before. Brazilian butt lifts are designed to improve your contour. Most of the fat that is transferred is at the mid and upper portion of your buttocks and would be unlikely to correct the problem you're describing.
In my San Francisco area practice we have used fat transfer to correct scars or significant lipoatrophy from surgery or trauma that can help cushion nerves in that area (sciatic typically). This technique would not significantly address the cosmetic issues a brazilian butt lift would address.
I hope this helps.
