Hey all,

I'm wondering if anyone else experiences this and has any advice. I have read a lot about CU and have similar symptoms but not quite. From what I read, people mostly get itchy and hives from being hot or sweaty. I experience insane itch when I am active in the winter time, say if the temperature is below 60 degrees and I'm walking vigorously or hiking outside. I will also itch if my skin is cold and I begin to exercise inside. Even once I warm up, I still itch. Unlike sufferers of CU, I don't typically sweat when this happens. I'm usually not exercising that much to sweat, so I'm not sure what this condition is.

For some background, I do recall feeling itchy during walks on chilly days during my childhood. And there were many summers when I would get heat rashes. And there was one summer in my early 20s (I'm 32 now) when I would fitness walk for a couple of hours and find my back covered in hives (and sweaty). That only lasted for the summer however.

So, any ideas? I haven't tried to treat this since I just started researching it. I didn't even realize it was a common problem. I've just avoided outdoor exercise in the winter, figuring it wasn't in the cards for me.

Thanks in advance for your thoughts!
