Suggest Treatment For Numbness And Pain In The Index Finger

My right index finger, at the tip gets cold, numb, blue and is painful, very frequently, and when I warm it up it is really painful, it is a bad ache down to the bone or a burning like sensation to the tip or my finger. My finger only bothers me when I am up and moving around, no problems at night, does not effect my sleep or anything but once I get up and start moving around, like putting on my make up and fixing my hair the symptoms start again. When I am at work it is worse. I use the computer a lot at work and it is very bothersome, I have to stop several times a day and massage or warm my hand. I thought maybe it was carpal tunnel syndrome, but I have never heard anyone complain of the just the index finger of the hand being effected
