i spray cold water on it (to stop the itch), dab dry and apply the same moisturiser I use for my stretch marks (to moisturise it and prevent it from getting bigger, hopefully)
use ice pack!!! it helps!
the idea is to ice until it is numb :')
i am having pregnancy rashes on my whole arms and belly and its spreading to my legs now. ice pack helps when its v itchy
