Loose skin removal following reconstruction

Hi all, I had Tram flap in June last year, and all in all really pleased with it. I saw my surgeon in October who says that I need to have further surgery to remove loose skin that has occured on my reconstructed breast, when I raise my arm it has a rippling effect, as well as have my nipple put on. Has anyone else had this loose skin thing??? I have a date for 14th Feb and altho Im having my pre op this Thursday and could ask the questions then, I just wondered if anyone out there had the same, if so did you have to have time off work???and if so for how long?

Thanks in advance
