Numbness in the thumbs and first two fingers, often accompanied by wrist drop, are symptoms of radial nerve damage. This is typically caused by handcuffs or rope digging into the gap between hand and wrist bone. On the opposite side, you have the ulnar which serves the pinky and 3rd finger. As my nerve damage study shows there are other vulnerable points up the arm.
@Wayhome I feel you are exaggerating the downside of circulation restriction in normal play. It takes some considerable time to cause tissue death and, I understand, the experience is excruciatingly painful if things were to get to that advanced stage. Circulation is often cut off during surgery for quite some time with no adverse effect. That is not to say that there are not dangers from pooled blood returning and causing toxic shock or oxygen starved tissue/nerves being made more vulnerable by the flood of oxygenated blood.
Nerve damage can happen quickly, without warning and can be permanent. Generally, recovery begins in days/weeks and there is little you can do except wait and not aggravate the condition. It is a question of allowing the nerve to regenerate. This happens at roughly 1mm per day but you can read more than you ever want to know about that here http://www.medscape.com/viewarticle/480071_5 Regeneration is not the same as return to function and this is why it can take weeks/months:
"Axonal regeneration is not synonymous with return of function. A process of maturation precedes functional recovery. Morphological changes of maturation proceed along the regenerating axon at a slower rate than axon regrowth and continue for a protracted periodas long as 1 year. Remyelination develops in a manner similar to that for developing nerve fibers, involving alignment of Schwann cells and encircling of the axon to form a multilamellated sheath. This process begins within 2 weeks of the onset of axonal regeneration and results in myelinated axons quite similar to the originals except with shortened internodes. The axon's diameter increases progressively until normal dimensions are reached, but this enlargement is dependent on the establishment of functional connections between the axon tip and the appropriate end organ."
