vaginal yeast infection
"I get repetitive yeast infections, so it took three treatments with Diflucan for three different infections before I realized that Diflucan was the thing that was causing the painful, blistering skin rash I was getting about once a month.  I was having what it is known as "fixed skin ulceration."  Ulcers in my mouth, blisters on my hands and leg, always in the same exact spots each time and always very painful.  No one told me there was even a chance that I was allergic to this medicine and when I sought treatment for the second and then third episodes, the doctors completely missed it.  There needs to be more information out there about this as the company only reports one previous person ever having this same reaction, yet it happened to me."
