you are massively deficient in vitamin d.
Actually I started taking 400 IU Vitamin D daily 1 1/2 years before this started. The hives and angioedema started at the end of January 08 and is still going on. The hives come out any place they feel like. They may come out on my upper torso and then come out on lower torso, or both. The angioedema effects my feet, hands, and arms mainly. The angioedema stays in my left arm most of the time. (My left arm swells up and down several times a day, but it never goes down all the way).
I have been tested for Celiac, Lupus, Thyroid, Allergies (both the 72+ scratch allergens and 50+ blood allergens tests done), Elevated Tryptase levels, Rheumatoid Arthritis, ANA Levels, etc. Everything came back normal or negative.
They do know that what is causing them is internal and not external (meaning it has nothing to do soaps, or contact allergens). My histamine levels are high and I have to watch out for foods very high in histamine (fermented foods mainly), because these foods just add to my already high levels of histamine.
