Anyone have allergic reaction after c-section

So I had my second c section. Told the doctors what I’m allergic to. Tegaderm, chlorahexadine, iodine, lots of other preps used. But I am still having a severe reaction post csection. My whole abdomen is like fire and in a blistery rash. Anyone ever experience this? All they gave me was hydrocortisone cream and Benadryl. Nothing helps and I am so itchy. On day 4.
