I woke up in the middle of the night with pain on my right arm, it felt like it was asleep. I rubbed on it to make go away. It did. But then I got this pain back. With out the pins and needles feeling. And I've had it for the past 2 hours and it hurts!! And I can't sleep. It's mainly in my elbow area, then it sends tingly feeling to my finger tips. I'm 20, healthy, so what can this be?
