Hives when you sweat..

I get hives easily when I sweat in the summer.

Especially, it stings and turns red where the arm bends.

Sometimes it extends all the way down the inside of the forearm below the elbow.

But it disappears quickly again.

When it hurts, applying Virmy feels cool and also helps it subside a little faster.

Since it disappears quickly, I don't think about going to the hospital.
