Sardar's body pain

Santa Singh went to the Doctor and complained that he was aching all over.
"Where exactly are you hurting?", asked the doctor.
Santa Singh replied, "All over my body, Doctor." He touched his left hand with his forefinger, "It hurts when I
touch here". He touched his right leg. "It hurts here also." He touched his back, arms, stomach - everywhere
and said it hurt in all places.
The doctor took some x-rays and said, "Santa Singh! I've caught your problem! You have a sprain in your
forefinger!"
