These are one of the funniest kind of jokes because the Medical profession is otherwise a serious profession.
Bholaji goes to the doctor and says "Doc, I ache all over. Every where I touch it hurts."

The doc says "Ok, touch your elbow."
Bholaji touches his elbow and winces in genuine pain.

The doc, surprised,says "touch your head."
Bholaji touches his head and jumps in agony.

The doc asks him to touch his knee and the same thing happens.
Every where Bholaji touches it hurts like hell.

The doc is stumped and orders a complete examination with X-rays etc... and tells Bhola to come back after two days.

Two days later Bhola comes back and the doctor says, "We've found your problem..."

"Oh yeah? what is it ?"

'You've broken your finger!'
