I don't know how else to describe it.

I'm getting random very severe bursts of pain in my left pinky. My left pinky only.

I've searched around. found posts of people having pains in the tip of their fingers. This is *NOT* in the tip of my finger. It is surely somewhere around the center of my pinky, right around where the joint is.

The pain is random. In between the bursts of pain, the pinky feels cold, similar to how your finger feels after you cut off blood circulation temporarily then restore it.

It even almost feels bruised to the touch.

Does anyone have any idea what this may be?
