Hi, I'm an obese diabetic, on metformin and losartin, and i sleep on my side with my head resting on my arm, which is usually under my pillow. When I wake up whichever arm I've been sleeping on is almost always numb. I have health anxiety and have gone to the dr about chest pains, which was attributed to stress/panic attacks after they did all sorts of tests to ensure my heart is fine. My question is, how concerned should I be about this? Is it a circulation issue? etc etc. Thank you.
