I get them now and then on the inside of my elbow and above, which I assume is from sleeping on said arm (I also get them from blood pressure cuffs, blood draw tourniquets and carrying bags on my arm there, so I don't think too much about it). But twice this week my entire forearm has been absolutely covered, with big patches on my upper arm. Starting to weird me out. I have to get blood tests done soon anyway, so I'll know sooner or later if something's up besides my giant melon head being too much for one arm to support. Just one more thing to bug me. Ugh.
