2 Months Post Op BA with Allergic Reaction to Neosporin, Thick Rash Around Scar? (photo)

I started neosporin on post op day 6 and continued to use for 1 week until it was confirmed that I was having an allergic reaction to it. I stopped and took an oral steroid for a few days. I started scar away (silicon sheets) at 2 weeks post op. The rash seems to disappear some days and then get really bad like now. At this point i am wondering if i should just completely stop using everything and just let my skin work the issues out of its own or if I should seek the help of a dermatologist.
