I Had Hive Breakout For About A Month. I Am

I had hive breakout for about a month. I am taking An allegra in the am and a zurtec in the pm. Also an Zantac once a day. I take a steroid 3X for 3 days, then 2X for 3 days and then 1X for 3 days. But once the steroid runs out... my hives are back. My Igg levels are low .. per the nurse at the doctors office. I cannot get an appt til October.

Also take a vit D3 and a multi-vit. daily
