Hey! I’m 4 weeks post op and I started doing mine! And when I say started I literally have done it once! I did one and got bored, haha so couldn’t be bothered to do the other!!! Im lazy… i know! But I now have feeling in my nipple on the boob I massaged!!! It’s so so strange! The day before hand I didn’t have feeling! So I suppose it can’t hurt too much as long as you aren’t going over board!! I’m now trying to massage the other one to get the feeling back too but it’s been stubborn!! I must sound mad!!xx
