I feel that maybe if someone can research on this topic, we can find a cure to this problem. My reason for thinking so? I’ve a strong reason for it. Whenever you are stressed/exercising/sweat adrenaline is released in your body. And I think adrenaline has got something to do with the hives. Much research is needed along these lines since only a small percentage of us(not all people) get these hives when adrenaline is released.
I hope may be someone who can help us stumbles on this post.
