Hang onto your doctor!Sometimes things like this turn out to be a big nothing. By that I mean the irritation clears up never to come back again. Every blood test comes back negative and the symptoms never recurr.
However. Your doctor has taken the situation seriously and is willing to do every reasonable test (and a few unreasonable ones by the sounds of things) to make sure you aren't dealing with something you need to do something about.
More importantly, he isn't treating you like a hypochondriac. He's being supportive and not just telling you to go home and forget about it.
There are many doctors out there that are like this, but unfortunately there are just as many who fall a tad short (or more than a tad).
My doctor is on the good list too. Unfortunately he isn't taking any new patients at the moment, otherwise I'd post his info.
Be well,
