Recently had an appointment for a "pain block" shot to deaden a nerve which was preventing full mobility in one of my joints.  I use no medications at all (script or OTC), vitamins, supplements, or anything like.  

Had to take a "piss test" on the chance I may have been there "shopping" for painkillers...cost the insurance company $700+ of which I had to shell out around $170...the actual DOC visit and procedure were extra. Doctors are obviously paranoid.  

This has to be a royal "pain" for folks who truly, legitimately,  depend on these medications.
