Hi,
I am now 8 wks and had this around 4 wks too, at first it was just in left but then a little on right too. I saw nurse and my surgeon and I had excess fluid which he drained out, he just squeezed breast and collected fluid and if ur still numb u dont even feel it. I had a little trouble with wound healing after too with a blister forming because of the fluid build up so its best to see nurse a soon as you can. But mine are healing nicely now its just sometimes the fluid does not reabsorb and oozes out xx
