Crazy Hives!

[Biciclista]

the only time I had hives it was stress induced. Someone gave me a box of baking soda and i took a bath in it

they went away in about day.

I had hives on and off for a year, about 13 years ago. They were on my arms and around the places where my clothes were tight against my skin (waistband, etc). Had lots of blood and skin tests and no one ever figured out the cause. I am still allergic to the same 3 things I have been allergic to my whole life and I didn't have any weird diseases. I do have asthma and allergies, but they weren't really acting up at the time.
Chalk it up to stress.

In high school, I got hives on my knees and elbows anytime I'd exercise and the air was a little bit cold. At the time everyone seemed completely baffled, and vaguely accusatory-like I was doing it on purpose- but now "cold urticaria" is a real diagnosis.
