question: During sleep, my arm begins to tingle and gets numb, especially at the thumb and opposing two fingers. The arm from shoulder to fingertips on occasion has a burning sensation which abates if I get up and move around. By flexing arm and hand, near normal feeling returns in a few minutes if I move around but keeps me awake nights. Is this a condition for a neurologist s attention? I am type 2 diabetic, recently diagnosed with polycythemia. Red cells now within normal range. DOB 10/20/20, active and mentally clear.
