I had severe hives over my whole body . My face got so bad the bridge if my nose was too swollen to wear glasses. My eyes were so swollen that i was unable to put on my contacts.
I always felt this was stress related because it occurred during deeply stressful periods of my life.
It went on for many years. Dr tried all sorts of things but the only thing that helped was ativan.
I became sick with many issues about 20 years into this when i had a thyroid test . It turns out i developed hashimotis thyroiditis. As soon as i started treating that, the hives stopped permanently. It turned out that for me and many others treating this thyroid problem stopped the hives.
I dont know if this will help at all but i am sharing in the hopes it will.
