<s>[INST] What s wrong with my mouth and tongue ? I have excess mucus. Feeling like I have to constantly swallow or clear my throat. The roof of my mouth looks like it s bruised and yellow in the back of my throat has red splotchy Kinda look to it but it s not painful. And then my tongue was white coated and all that stuff is scraping off and now I can feel my taste buds because my tongue is bumpy and it hurts to eat. I am a smoker, and I brush my teeth morning and night and floss everyday.. I m hydrated my urine is almost clear. [/INST] Hi. Thanks for the query. Your symptoms are clearly pointing towards fungal infection in mouth and the white coating is due to yeast/fungal growth over the tongue. The condition is known as Oral Thrush. The inflammation over the roof of the mouth is also due to infection. As you are a smoker, thrush is common and if you continue to smoke it can also worsen the infection. So first you should quit smoking. In case if you are addicted you can go for nicotine replacement therapy in the form of nicotine patches and gums. Fir thrush you can gargle with specialized mouthwash like Statin mouthwash that is an antifungal composition. Suck Clotrimazole lozenges. You can also be advised oral antifungal medicines like Fluconazole. Chat Doctor. . Clean your tongue daily with a tongue cleaner. Eat plenty of probiotics like Yogurt and garlic as they are helpful and clearing infection faster. Hope this helps. Regards. </s>
