I read somewhere online that holding a hot spoon to the area could burn up the proteins causing the itching or something. I don't want to wait for a spoon to heat up, so I use a dryer and stop once it starts to sear. 

Itching naturally makes everyone want to scratch, and I guess cause ourselves pain to make it go away. But I'm a very logical, kind of OCD person, and feel like my repressed self-harm urges come out full force once I have a "good" reason for it. 

I scratch furiously and hard, sometimes with a comb, and almost always until it starts to bleed. Perhaps it "bleeds out" the chemical making me itch. I feel like, if I ever cut myself, it will be on a bug bite. At times I've even pondered purposely getting bug bites just for the pleasure of burning or ripping at them.
