Some ideas.: Start with diagnosis. If numb, cold, or pale, it could be circulation. If it happens in the cold that might be raynauds. If mostly numb, could be a nerve problem instead. Poor circulation in one hand (usually left) can come from a kink in an artery higher up. The clue there is the blood pressure on the affected arm will be lower than the other side. Your doctor can try to pinpoint the problem.

Unlikely: First, you should have a non-invasive vascular examination to confirm or rule out "low circulation in your hand." this is very unlikely because we have dual circulation to the hand and it's very rare to have both sources impaired, even in the most advanced cases of vascular disease.
