Urticaria
"Had hives nearly every day for 3 weeks (at first I thought I was getting bug bites).  Went to the Doc and she told me to try Zyrtec.  Last night was the first time in 3 weeks I&#039;ve been hives and itch-free.  It&#039;s amazing.  I just wish I could find out what&#039;s causing the outbreaks!"
