Greetings, I m 64 years old, both the index fingers left an right the 1st joint with the fingernail, when tapped even lightly give me excruciating pain lasting for a minute or more depending on how much of a tap they recieve, what would you think ? I also have other locations for intense pain, left foot on the outside , right thumbjoint in palm of hand. But the 2 index fingers have me seeing STARTS when I tap or bump them.
