Hi…You have had the rash for a year ? Is it all over ? I had 5 infusions of Keytrua and the rash is all over my arms, legs, back & chest. The sores are big and swollen. If I bump into something it hurts 100% worse than when I didn't have the rash. Please ….has your rash subsided at all ? I have been to 3 Dermatologists , have used 3 steriod creams, prednisone for days. Am very miserable to think my life has changed so drastically.
