Don’t forget to keep a diary, writing down your activities every day, along with when and where (on your body) hives occur, and what you ate that day.

Bring the trigger list and diary with you to your doctor’s appointments.

If you’ve had hives for over 6 weeks without any trigger you probably have CIU.
