Started 3 4 years back that my some body part like stomach itch and I can’t help to scratch so it left a like dark patch after that.

 

Now 2days ago my leg and hand start to itch its so frustrating..  no ideas what’s making it itch..

 

im thinking of seeing dermatologist (specialize in itchy skin/sensitive skin – dk if I really have sensitive skin or not), but I hope it’ll to solve the problem..
