I heard that reflexology (manipulation of the feet) can relieve many ailments. Can it get rid of a pain in the a$$?

My foot reflexes have been known to do that:

Depending on where in the ass. 

The feet contain two types of lines to run to get relief.  The nerves, which you are familiar with that actually conduct electric impulses, and the impulses themselves which is the electric energy.  Those lines are meridian lines and if you can manipulate them correctly, you get dramatic results and are hailed as a Shiatsu Master.

Or an acupuncturist if you use the needles.

The acupuncturist could most certainly address the butt no matter what area, no matter what layer.  It is all fascia, nerve and muscle.    He/she would be the easiest to find and see reviews that make sense to you.

No, that's what divorce is for.

Nah, for that you need a gun.

Just be careful, the cops can be a pain too,
