I was sent for an ultrasound which showed a huge amount of fluid around the implant...the radiologist (the same biopsy man) wasn't going to contemplate draining and said it should be left to go away on its own but my hero Mr G grabbed the rains and did the job himself. 150mls of fluid later and a much deflated boob, I feel so much better.
No explanation as to why this has happened, just one of those things, but Mr G wasn't impressed I was put through a biopsy. He has no concerns about the results, apparently my lymph nodes looked abnormal but that was to be expected given the boob issues. Got to go back on Thursday to check the boob behaves.
