I suffers from endometriosis for 20 years before I had a hysterectomy, so I've been on a crazy roller coaster of hormones, but only had hives 6 months after my hystorectomy. 

However, I have 3 daughters and the youngest two have been dealing with hives.

The 17 year old seems to get them on her legs only- she's an avid soccer player- but she seems to be more prone to ovarian cysts and won't stay on BC because it makes her sick.

The 12 year old is worse. Constant hives over her whole body for almost 8 weeks now (including eyelids). We are running the gammet of docs and specialists trying to get them under control. She's been doing the Zantac, Claritin, singularity and benedryl cocktail, but isn't sleeping well. Blood tests appear normal. We see a dermatologist next week and an allergist soon. 

Any thoughts?
