I have been sleeping sitting up right all the way through, im 4 weeks and 4 days post op, last night I had neck ache and ended up chucking most of my pillows off the bed and layed on my back but ended up on my side, when is it okay for us to sleep on our side? Or even on my back? Is it okay now or should be sleeping upright until the 6 week check up? Or 7 weeks for me as thats when my apointment is haha xxx
