<s>[INST] Hi, could you solve this for me please? My tongue feels swollen and stings as there are a few white lumpy hard spots on it. I have ulcers/spots: one on the inside of my lip, two on my gums and one underneath my tongue. My mouth seems to be producing more saliva than usual but it hurts to swallow - feels like I have huge lump in my throat. It is uncomfortable to talk, eat and swallow. I am probably just run down because I have just finished my exams, but I just thought I would ask. Thank you. [/INST] Hello dear, Thank you for your contact to Chat Doctor. I read and understand your concern. I am Chat Doctor answering your concern. It looks like that it is a kind of fungal/ yeast infection. But to confirm the cause I advise you to do microscopic examination from the lesion like Grams staining. This will tell us the exact etiological agent and can help cure us the infection with minimum efforts. But till the result came you can take the fluconazole 150 mg tablet once a week. When the result cameo can change the Chat Doctor. Please also test your self for the HIV and diabetes. These is the common cause for the fungal infection in the oral cavity. So once clear from the above infection you will be readily cured. Please maintain good oral hygiene, medicine mouthwash can be used. It will help maintaining the good oral hygiene. Avoid spicy foods, bland diet consisting of high protein and carboy </s>
