A few weeks ago, I was diagnosed with angular chelitis. Was prescribed nystatin and within 24 hours my symptoms were relieved. I used it for a few days and stopped thinking it was all cleared up. five days later, it flared up severely. IT is spread to my chin and of course lips. And even my tongue is sore . I a back to the nystatin . This is day 3 and it doesn t seem to be helping. The burning, itching, and pain are horrible. And of course, it s a holiday weekend! Any suggestions?
