There have been several times over the past few months that I feel a sharp pain (suddenly) in the index finger on my left hand - it can last up to two days - the pain becomes intense and then it is like an explosion at the tip of the index finger and then the index finger starts to turn black - usually around the fingernail first then spreads to the rest of the finger stopping at the knuckle. It hurts a lot.
