Experience of mast with extended lattimus dorsal flap ?

Has anyone had this op with immediate reconstruction?

My daughter had the op 4 years ago and has now had a second one on her other breast - but experiencing a lot of probs this time -infection in the seroma and ongoing pain and discomfort.

She is 5 weeks post surgery and is getting very fed-up with the repeat visits to the hospital , the continuing pain and the lack of movement despite really working at the physio exercises.

Has anyone else had this op twice- I understand it is quite unusual.
