Feeling like I can feel blood moving around in my arm

[Coldnights]

And then I develop tiny red spots after this feeling. I’m not sure if I need to contact my gp or not.

Bumping any advice appreciated.

Yes. Any blood pumping, rash, should be checked out.

Best waste a bit if their time than be sorry. Ring GP or 111 now.

That should be blood pimpling - damn autocorrect!
