Upper arms and left calf itchy on and off.

as the title says, I've been dealing with this on and off for the past month and its driving me crazy. I keep thinking its diabetes but I haven't experienced any other symptoms that would be related to that condition. has anyone else experienced this? I'm 27 years old and 186 pounds

The itching can be related to poor circulation. :(

I dont see how. I'm on blood thinners so I shouldn't be having problems with circulation.

I get it occasionally on my ankles so I saw my GP who said it is a symptom of poor circulation. May not be in your case but best to seek GP advice.
