My tongue is sick and my taster is off June 6 2011

My tongue has been bothering me for about 2 weeks. It is tender and nothing tastes right. I told Dr. Moore about this. Since, I've been on 2 courses of Z-Pack antibiotics (Azithromycin 250 mg capsules) one taken from April 23 to April 27, 2011 for a sinus infection and the second course from June 1 to June 5, 2011 for sinus again, I might have a yeast infection. However, Dr. Moore is not convinced that it is yeast, but gave me a 5-day course of Diflucan 100mg one per day by mouth to see if it helped my ailing tongue and taste. I started the Diflucan tonight.
