Hi Issy,
I had mx 1st December with immediate reconstruction using a dermal sling, so I don’t know if the type of sling can make a difference. I am/was a 32G so I have a huge difference between my foob and natural breast (getting reduction and lift surgery in a month or so) but at first I found the swelling was so much that they really didn’t look that different in size. 8 weeks on and the swellings gone down a lot and I’ve noticed the shape as changed over the weeks. So you probably find as the swelling reduces and it all settles it’ll drop and change a bit more, hopefully giving you more balance. Good luck with your recovery x
