Is a breast reduction rash common at 2 months post-op? (Photos)

It is  common to have some kind of rash after breast reduction. The rash may represent an allergic reaction, say, to tape, but the distribution of your redness does not seem to indicate this. You may also have a fungal infection. I suggest seen sooner, rather than later.  Often, a steroid cream could decrease your symptoms as well as redness and allow earlier healing.

This may be organic in nature, but allergic reaction from adhesives may be the cause.  An allergic reaction after breast augmentation and lift may be due to adhesive, tape, steristrips, the garment, antibiotic ointment, or any number of things.  If there is no infection, oral or topical steroids can be offered.   A comfortable t-shirt or the like worn underneath the compression bra usually tends to help with irritation and comfort.
