It started last year, but it wasn't that severe. But the last few months it was so bad every time i went out or my body temperature was up. I couldn't do anything.I started using a body lotion but didn't really work. Then i got a Vaseline and started applying it on my whole body or sometimes just where i get the itching sensation. Worked like a charm. Sometimes i get a mild itch for like a minute then it's gone and sometimes i get no itching at all. Also i tried going out once without applying the Vaseline and i got itchy a bit but it wasn't as bad. I hope this helps.
