A 28-year-old female presented with complaints of mouth ulcers, burning sensation in the oral cavity, and throat discomfort persisting for the past 4 months. The patient's CBC results are within normal limits, and vitamin B12 levels are at 738 pg/ml. The throat endoscopy indicates candidiasis at the base of the tongue and posterior laryngitis, suggesting GERD. The condition keeps recurring despite being prescribed kenacort, lexanox, zytee L gel, and candid mouth paint. Kindly suggest an appropriate diagnosis and recommend a suitable course of treatment.
