You might also try some orange juice off and on during the day, as it also helps to open capillaries. But DO get checked for your arm.
I’ve had angina for 35+ years, and although my heart is very strong, my circulation is poor, and has been since I was a short person. Still, if I experience anything unusual (for me) I have it checked.
You are in my prayers!
How was your circulation before you became a short person?
