question: I have allergy to balsam of Peru and it is found in so many products. My worse rash lasted 5months before patch test identified it. It was oranges, and when I stopped eating one every night the rash started healing. This allergy happened after several surgeries starting in2015. 4 bypass, ruptured gallbladder, paralyzed vocal cord from trying to remove stones by my throat, lost 2 of my bypass, had 3 stints to make up for 2 losses, Carotoid artery unblocked and another stink put in Nov2017. Do you think my surgeries caused this. I have always eaten oranges and tomatoes but now I have outbreaks and keep record of what I eat.
