Greg, Merrill is probably right. Yeast infection. I've had that once before too. I don't believe I took antibiotics, but I did use a prescription anti-fungal cream. You should definitely see your doctor as soon as you can, but until then try using an over-the-counter antifungal cream or ointment. It won't clear things up, but might keep it in check until your doctor can prescribe something stronger.
Also, there are natural antifungals, if you want to start down that route. I was drinking grapefruit seed extract [GSE] for a while, but it's so bitter that it's literally difficult to swallow. Get well soon, Don.
