I have a painful rash on my right wrist, likely from a minor burn caused by hot mustard oil while cooking. Initially, it was red and irritated, but now there's a round patch with a white center and surrounding redness. The skin is slightly peeling, and I feel pain especially when rotating my wrist. I had applied Mometasone Furoate cream for a couple of days, but the pain and appearance didn’t improve much. I’ve also been cleaning the area and keeping it covered. Please advise on the best course of treatment.
