I get bouts of hive when my body heats up but I’m not able to sweat, for example, in cold weather, under duress, any extreme emotion. And the pain is best described as hot needles being pushed out of my skin. The pain travels downward in waves from my face to my chest. On one occasion I collapsed from the pain. It’s twice as worse as a beesting and it’s constant.
Why is something that is caused by something as innocuous as histamine capable of driving me to my knees?
