I had a LBL 6 days ago and I'm unable to fully stretch my back. I put pillows to raise my back and sometimes I find it very comfortable to sleep in a siting position. I can't sleep on my sides at all but the only thing that really annoys me now is that my buttock hurt a lot due to the fact that I'm sitting on it all the time while in a chair or on the couch or even the bed. Is there any other position that could make me feel more comfortable? Thanks
