Anyone know what causes a itchy rash on both arms and face with swollen eyes?
The rash started with tiny tac size itchy spots that covered my arms then my eyes started to swell shut. Took benadryl and used benadryl spray on my arms.
My arms are still covered with a red rash and eyes are still swollen and I just don't feel 100%

Any ideas? I just got here sunday night and haven't been in the water yet. I have no known food allergies. What could this be?
