Hello, I was wondering if anyone else experiences this and should I be worried. I often wake up at night with a numb arm, which once I shake it off, the feeling returns with some pins and needles. It's often when I've slept on that arm so I haven't been too concerned. But last night I awoke with part of my right cheek numb. I felt that side of my face, and I could feel the pillow lines on it, so I knew I had been sleeping on it. Within 30 seconds, the sensation returned. Should I be worried about this? I didn't think sleeping on one side of my face could do this. No other health conditions accept iron deficiency anemia. Has anyone else experienced this where it hasn't turned out to be terrible disease?!
