It finally has a name

I have had this condition since I was a teenager but it became more prominent when I was in college. I cannot walk any long distances or extended period of time without my legs itching. It's my thighs mainly but it will spread to my butt and sometimes my stomach. I asked my mom about it and she said she has the same condition and my aunt did too. I'm wondering now if this is hereditary. I decided to finally look it up today and found out that it's called Cholinergic urticaria or exercise urticaria.

Cholinergic urticaria It is the rise in body temperature that produces the itching, swelling, and small hives that some people experience. People who have this may also experience the same reaction in hot tubs, saunas, and see that they are more likely to get it on hot days. This rarely leads to anaphylaxis - the life-threatening drop in blood pressure that can be fatal in major allergic reactions.

I don't have a problem with heat or humidity making me itch. Its just the walking thing and it's good to know that I'm not weird.
