Meeting Dr. Coulter

Rheumy says Mr. Plaquenil is slacking off.  He upped the dose 20 mg.  Hope that perks him up a bit.
Rheumy puts me on Hydrocodone. 
Rheumy runs more blood tests (one can never have too many tests).  Explains to me there is a difference between Mixed Connective Tissue Disease, Undifferentiated Connective Tissue Disease and Lupus.  Well, maybe to a Rheumatalogists there is.
Rheumy doesn't seem to like my GP's course of action, or lack there of.  I show him my beloved iPad.  (side note: calendar is awesome for tracking pain, meds, butt troubles, etc.  Little bullet points, very easy to read)  He does not agree to me taking Imodium as long as I need to, no problem.  He wants to know what is causing butt troubles.
So now I am on my way to a consult with Dr. Coulter.  It snowed 3 inches last night and I get to drive 19.7 miles to his office to meet him.  I'm a little leary.  I have to have a colonoscopy, yeah me.  Does anyone else find it creepy that a guy would spend so much time and money going to school to spend his life looking up peoples butts?
