:hug: Oh yes, I've had it several times, it's terrible! Yogurt and the like helps but when you are immune suppressed on prednisone you really need the antifungal prescription meds to kick it.
I needed prescription Mycelex oral trouches, which is like a lozenge, four times a day for three weeks. I also added really high level probiotic supplements, too.
Also, buy cheap toothbrushes and toss them every few days so you don't reinfect your mouth with them, and brushing with sensitive toothpaste helps a little with the soreness-for me regular toothpaste burned like fire. Hope this helps
