Still in pain 8 weeks post-op lipo of back and flanks. Is this permanent?

I am 8 week’s post op. Lipo of flanks and lower back. I have had to go back and get fluid drained out of my back 3 times. Last one was a couple weeks ago. I am still in pain in places on my back; sore to the touch, numbness and most of all a painful tearing and burning sensation when I move. I’m starting to worry that this may be permanent? Can anyone relate or explain what s happening? Help! I am a 46yo female in pretty good health otherwise.
