Red spots under skin on fingers

I noticed a couple subcutaneous red spots on my fingers a couple weeks ago and it was sensitive to pressure and recently more of these have showed up.  They are pretty sensitive and are now showing up on all five fingers on my right hand.  They are mostly on the pads of the fingers with a couple on the sides and one on my index finger that feels and almost looks like a hangnail.    These spots are limited to my right hand only.  On my middle finger the red spots almost form a ring.  Ideas?
