urticaria
"I had hives for 3 weeks and I was completely miserable! I was put on steroids for 3 days and they came back as soon as I quit them.  I was taking Benadryl everyday and was still so itchy. About ready to go nuts I researched and researched things to try.  Into week 3 with the hives I started taking Vitamin C, Vitamin D and Vitamin B12 and drinking green tea everyday.  Took a Zyrtec one morning and my hives were cleared by evening. I have been taking 1 a day for 3 days now and I'm hive free..feeling great."
