Headaches
A guy is suffering from severe headaches for years with no relief.
After trying all the usual cures he's referred to a headache specialist
by his family doctor.  The doctor asks him what his symptoms are and he
replies, "I get these blinding headaches; kind of like a knife across my
scalp  and.."
He is interrupted by the doctor, "And a heavy throbbing right behind
the left ear?
"Yes! Exactly! How did you know?"
"Well I am the world's greatest headache specialist, you know. But
I, myself, suffered from that same type of headache for many years. It
is caused by a tension in the scalp muscles. This is how I cured it:
Every day I would give my wife oral sex.  When she came she would
squeeze her legs together with all her strength, and  the pressure
would relieve the tension in my head. Try that every day for two weeks
and come back and let me know how it goes."
Two weeks go by and the man is back, "Well, how do you feel?"
"Doc, I'm a new man! I feel great! I haven't had a single headache
since I started this treatment! I can't thank you enough.  Oh and, by the way,
you have a lovely home."
