I am 6 days post op wearing my faja with the foams, ab board and back board 23 hours of the day. I find that during the day my back doesn't hurt as much but in the night I wake up with some the discomfort of back pains. I thought it was the back board so I took out the back board and sleep with everything else on but the pain is still there. What should I do and is this normal? I read that the faja and back board helps correct slouched posture is that the reason I am feeling pains?
