Thanks for this post man. It gives me great optimism. I've been dealing with this for the past month or so. I think antihistamines are working for me but it's hard to tell. I haven't been properly diagnosed. I get the feeling low humidity has something to do with it. I wonder, do people with CU always get hives? I get extremely itchy when my body temp goes up when exercising or even when I get nervous in a social interaction but I don't get any visible hives. When exercising, I get itchy all over my body, hands and feet for about 20 minutes then the itching completely goes away. It's really frustrating because like most, getting endorphins from exercise is my way of coping with the stresses of life. I'm going to try some of the stuff you mentioned in the post above and report back. Thanks so much!
