What does red breast syndrome look like ?

Red breast syndrome is usually associated with acellular dermal matrix (Alloderm, strattice, etc) more than with the actual implants.  It's a delayed hypersensitivity reaction and usually involves the part of the breast that overlies the Alloderm.  It could also be completely unrelated to the Alloderm and could represent a late infection.  It sounds like your surgeon is following you closely.  Ask him or her what they think about red breast syndrome when you see him/her again.
