In brief: Impingements

Intermittent nerve compression can cause.
Pinching occurs at costoclavicular dimension, true thoracic outlet. Raising arm unconsciously during sleep causes this space to close by a few millimeters, pinching main nerve ; artery to arm. Ulnar parasthesias (crawly tingling feelings) occur in pinky side of hand. This dynamic is called thoracic outlet syndrome (tos). See my discussion at quora.Com.

In brief: Numbness arm & hand

What you're experiencing indicates a nerve problem arising from compression or impingment arising either in your armpit or up in the neck.
Consult a neurologist.

In brief: Periodic nerve comp

Most commonly at wrist (carpal tunnel), but could be at elbow (cubital tunnel), shoulder (thoracic outlet).
If worse with arm elevated, points to tos, but better with arm elevated, points to neck.
