Is it normal to feel hot burning sensation 3 months after liposuction?

I’m 3 month post op tummy tuck and lipo. I still wear my faja day and night I’m jut not comfortable without it yet. While I sleep on my back in the middle of the night my lower back feels hot and bums. I have to loosen my faja and take off the blankets and sleep on my side to help with pain. The cold air helps . I do not feel this during the day while I’m standing, siting or walking it’s only while I sleep. During the day it’s very minimal and tiny shocks here and there.
