Post BR 3.5 months. On my LUQ (directly on my side, about 4" below my furthest surgical incision, is a pinkish discoloration and a palpable lump. Has been there for 6 weeks. Breast doc said she felt it was unrelated to surgery. Primary care doc had an US and CT done. CT report says "peripherally calcified nodule in left flank which could have been a hematoma." Is this a) a big deal?; b) likely from drainage post-surgery? And is there anything I need to do about it? PC doc seems unknowledgeable.
