Has anyone suggested "thrush" or oral candida? The yellow/white color and white bumps are a dead ringer for it. Adults get it as well as children and Ive read that severe acid reflux or the like can aggaravate it. Usually its treated successfully with fluconazole, clotrimazole, ketoconazole, or nystatin.A decent doc can usually eyeball it and diagnose it, but they can also take a little scrape and do a culture to confirm if its actually oral candida. Has your doc done this yet?
