What can I do to prevent alarplasty scars from getting worse two months post op? The base of the incision seems to be irritated.

My surgeon performed an alarplasty along with my Rhinoplasty without telling me prior to surgery. I didn't even know what an alarplasty was until the day AFTER my surgery. Had I known what it was I wouldn't have had it done because I didn't have necessarily wide nostrils to begin with. Now I'm noticing my left nostril base incision area looks red and raised. It doesn't burn or anything but I'm scared it's going to get worse. What can I do?
