Here's an odd one for you

[teddybears4ever2]

I used to be able to eat all the blueberries I wanted to.  One day I started eating them in an ice cream sundae, and of the blue my wrists started to grow hives.  I have never had this issue with any other berry in my life.  
For awhile it wasn't that bad.  Now I can't touch anyone who is drinking or eating anything with blueberries in it or I will break out in hives on my wrists.  I am wondering what brought this on so fast? Why just my wrists and nothing else?   That also makes very little sense.

Hi, welcome to the forum, you may be allergic to blue berries. Allergic reactions can manifest as various forms which includes itching, rash, hives, breathing difficulty, stomach pain, selective areas can be involved. May be due to poor skin integrity in the wrist area or presence of any other allergen which is in contact with wrist.  

As allergic reactions are IgE mediated, blood tests will show increase in these levels secondary to a food allergy. The problem with the food allergy testing is sometimes the amount of food taken may be not sufficient to elicit any allergic reactions.
When such food is consumed in large quantities can elicit allergic reaction in the form of hives, redness of skin, itching etc. You need to note down such food also in your diary and avoid the intake in future.

I suggest you to consult skin specialist/ immunologist for further line of management. Take care and regards.

maybe it was something other than the berries?
