Looking for Chronic Urticaria Treatment Advice

I have had chronic idiopathic urticaria since I was 11 (6 years). I got my first period about a month after I started showing symptoms and I tend to have flares more when I’m on my period, so it’s likely hormone related. I have lots of triggers (heat, saltwater, stress, latex, artificial dyes, etc) but avoiding them isn’t too much trouble. I also keep ice packs and lidocaine in the fridge for flares, and I like keeping colloidal oatmeal and Nivea in shower body lotion around for in the bath, too. Mine has gotten progressively worse over the years, but since I was so young when I first got sick, my case is a bit abnormal. Most cases last between 6 months and 5 years :)
