I hope your doctor can give you SOME kind of answer. It just seems odd that you've had this for about 4 years and she doesn't seem concerned. Is the upcoming appt with the same dr?
My family took a vacation to Vermont MANY years ago--we were all stunned at how green the whole place was. We visited Burlington, Montpelier and Wardsboro.
But, I digress...
Please let us know how your appointment goes.
