hi, i remember getting real bad back-ache (and bum ache!!) from having to sleep upright. After about 2 weeks, i gradually went back down to my normal 2 pillows. I tried laying on my side at 3 weeks, but it felt so uncomfortable, but by the time i was 4 weeks post op it was fine. The weeks will fly by…. it’s been 14 months since i had my ba, can’t believe where that time has gone! Take care girls xx
