Severe pain in one fingertip?

For the last few weeks, I've been having increasingly frequent sharp, stabbing pain under my fingernail on my left index finger. It makes me wince every time. I also have a strange, semi-numb feeling on the palm side of that same fingertip. The fingernail looks nice and healthy. I've had a digital mucous cyst on my right index finger (which was removed surgically but is back almost as big).  Both of these fingers have large bumps or swellings on them at the joint closest to the fingernail. The left one that's been hurting so much seems to be very slightly redder than usual and a tiny bit swollen, but nothing else really looks abnormal. It's getting harder to use the left index finger for much of anything (including typing) without increasing the pain. Is this something I should have a dr. look at asap? (My regular doctor won't be available for another week.) TIA for any replies. marilano

It seems to me that it is a 'glomus tumor'. It typically appears below the nailbed, and shows the symptoms of severe throbbing pain, tenderness and sensitivity to cold.
