Has anyone seen a reaction like this?

Allergic reactions can be scary to experience and witness in ourselves and our loved ones. Especially when the allergic reaction looks or feels different than what we have seen or experienced before. Has anyone here ever witnessed or experienced a "new" or unexpected allergic reaction that was unlike past experiences?

Help us spread awareness and share knowledge together by posting a picture of your "new" or unexpected allergic reaction to see if others in the community have experienced something similar in their past!

  1. I've been allergic to peanuts (but not tree nuts) my whole life, I thought I knew my reactions like the back of my hand. Then in college I encountered communal peanut butter in the cafeteria (which I tried fighting multiple times to no avail). One day I sat next to my friend who had peanut butter covered apples. Big mistake, the smell alone made me nauseous and by the time I got back to my dorm room I had a small amount of hives on my arm. I had to take a Benadryl. I had a private room accommodation because of this but the hives from the smell was new. Now I know that once I smell, touch or ingest peanuts I will get sick.

    1. yes there were some side dishes to eat. My dad even felt so bad that we went to lunch the next day.

    2. I'm glad to hear you were able to enjoy some side dishes! And how kind of your dad to take you to lunch the next day. Having supportive family and friends is so important! -Alexa (Allergies.net moderator)

  2. I find that nuts which are old smell different, and I think the oils in them deteriorate and I get mouth ulcers. Any hot pepper will do the same, but bell peppers are okay. There is a dental paste some allergists and dentists are familiar with, that I use, and my ulcers begin to heal in two or three days.

    1. , that's really interesting! I think you might be on to something about the oils in old nuts deteriorating. And thanks for mentioning the dental paste! I have not heard of it before, but now I learned something new today so thank you!

  3. I've had another one time allergic reaction, it felt like someone was squeezing my throat tightly. That was when I was allergic to flagyl.

    1. Oh gosh, that is so terrifying. The worst is that feeling when you can breath or catch your breath. Sorry you went through that. At least now you know to stay away from Flagyl. -Elizabeth (team member)

  4. Hi. Around two weeks ago I had an allergic reaction that presented itself with a slight rash on my neck that became itcht. A while later it spread to my right arm and it affected my breathing. It definitely was different than my usual allergic reactions.

    1. Thankfully its been a one time thing. Reactions are always a bit frightening. -Elizabeth (team member)

    2. I've had something similar happen. I learned in recent years that my allergic reactions are heavily sensory induced (touch, taste and smell, with ingestion being the worst). I came back from lunch with a dorm mate from being around peanut butter once. I had felt nauseous from the smell and I got back to my dorm and looked at my arm. I had a nickel sized mark on my forearm.
