A strange itch at the tip of my fingers?

I feel a strange itch at the tip of my fingers similar to when you sit down deeply and your feet arent irrigated next to blood correctly, the thing is it starts simultaneously at adjectives my fingers...what could it be , any ideas - a solution to this would be great! :) Could be an allergic response to some med you may be taking, the start of carpul tunnel, poor circulation, any number of things.
Please make an appt. beside your DR. asap to get checked.
