I had an anaphylactic reaction to almonds. I usally always read the label but mistakenly assumed that since another variety of the chocolate bar was safe that the one I had was safe. It said may contain almonds. My face swelled up and my throat became tight. I used my epi pen and went to the ER. They gave me Benadryl. I was there a few hours on a chair in the hallway because there were no rooms. We have a doctor shortage. The ER doctor would check on me. She said to take Benadryl for the next 24 to 48 hours. I get anaphylaxis from tree nuts, strawberries, peppers and CT contrast dye.
