3 months post op, I have chronic back pain ever since I had lipo done. Is this normal?

i had lipo to my back and a tummy tuck done almost 3 mths ago. Ever since the lipo on my back I have been experiencing chronic back pain. My surgeon says this is very unusual. It's feels like my tissues/nerves have been damaged in some way. Whenever I move I get a spasm of pain. If I'm active it's not so bad, but the sec I rest ie sitting or sleeping and I move from one position to another I get a spasm of pain - it's like a heat/burning sensation. Any ideas what the cause is and what remedy.
