The rash you developed after ceaserian operation and coming at home may be either allergic dermatitis
or drug reaction. You should contact first to your gynaec and then dermatologist
for perfect diagnosis.you take antihistaminics and steroids
in tappering dose, but after consulting the dermatologist. Apply combined cream of mild steroid and antibiotics. Keep the area clean and dry. Avoid soap bath. You may use dettol
in water for bath. I hope you got my answer...
