Any advice on prawn allergy? My 5 yo boy is having puffy/swollen eyes due to his food allergy to prawn. I have given him manuka joney and lemon juice to help reduce the puffy eyes. My question is: will the puffy eyes go away by itself after a while? It's been 3 hours since he has had the puffy eyes. His PD is already closed so can't bring him to PD today. :(
