hi , thank you , i have a terrible scratching in my upper body,both in front and back,an itching that could last up to 30 minutes,and normally happens when it is hot outside or when i feel hot and sweating.the scartching starts in one small place, i scarth it and it moves to some other point and so on, there is no visible rush on my skin or any bleeding or anything.

agin thank you for your help,i had this for more than 8 years now.
