I am day 3 post op after having a breast augmentation and everything is healing fine but I have noticed a ptc of my bum above my left buttock is numb. Day 1 and 2 I was pretty much bed bound and I've been sleeping elevated on my back. My bum kept going numb so I had to wriggle about a bit but now even though I've been up most of the day moving about its still numb??? Can anyone give some advice please? Thank you!
