mymittens, only just read this thread but wanted to try and reassure you.
I had a breast reduction 2 years ago. I had to have a masectomy on the left breast with immediate reconstruction from my tummy. As I was a 34F I was recommended to have a reduction on the right side at the same time.
I know this isn't exactly the same as you, however, immediately after the op I had a lot of 'bumpiness' and swelling, particularly on the reduced breast. At my post op check up it was evident that one breast was significantly larger (the reconstructed one) than the other.
Over the last 18 months I've had what I would call 'touch ups' - I should say the reason for it being so long is due to having chemo in the middle!
I had a small operation to remove a little excess skin underneath both breasts to make a smoother 'crease' and a little lipo on the reconstructed breast and fat injection on the reduced breast.
My 'boobs' now look great and although it took more than one procedure to get there, it was worth it. I am now a 34D - M & S bra advisors have been a god send helping me choose the right style bra for my slightly differing sizes.
You could try doing some 'arm brushes' on the arm that has the swollen breast. I found it reduced the swelling.
I'm sure once everything has settled you will feel happier - my surgeon told me it was 9 months before they would completely settle and at that point what you saw in the mirror was what you got! It was only then he would look at tidying anything.
Sorry for the long post but HTH.
