Itchy because of hives on my neckㅠ

Is it three years ago..?

With the groom's friends and couples during the summer

I went to the sea for a trip.

That day, the women tried to look like they had something going on.

I matched them with cheap muffler scarves.

Everyone else is fine, but only I am not.

It turns red and spreads throughout the neck.

I had a really hard time with heat rashㅠ

Since then, every summer, other places are fine, but

The area around the neck where a heat rash had appeared is bumpy.

There are things that sting..

I applied aloe and also went to the dermatologist.

It doesn't completely disappear..

How do you manage heat rash?
