I Have Severe Hives/eczema /rash/itching For About 9 Months. Was

I have severe hives/eczema /rash/itching for about 9 months. Was under care of dermatologist and treated with steroids and UV light treatments (approximately 50) to no avail. Dermatology referred me to Immunology. Immunology is currently starting a regiment of test to see if I qualify for Xolair injections. I just read about Bacid and eczema and wonder if my symptons are those of "Bacid and eszema". Thank you for any help.
