It sounds like your in love....
But seriously, the hand think sounds similar to something i have in my feet, but that is due to partial frostbite of 3 of my toes, so i would assume its not the same cause as that (they also do a whole stinging thing two), but if you get the two symptoms in unison it would make me think of a restrictive circulatory syndrome - not that i'm a medical prof or anything, but if it keeps going maybe think about having a chat to your doc, or maybe there is some sort of online medical forum you could try....
