[|Human|] Hi, I have an invisible sore/ patch in my mouth . It is located right under my lip. I can feel it with my tongue and it hurts, but I can t see it when I look in the mirror. I have had it for at least one month. Do you have any idea what it is or what I can do about it?
[|AI|]  Hello and welcome, do you have the habit of tobacco/pan chewing?then the patch may be related to any precancerous lesions like leukoplakia or oral submucous fibrosis. Steroids are the preferred Chat Doctor. If this is not the cause, then it may be authors ulcer type.it can be treated by tab.flan zen and tab.alone.avoid intake of spicy and sour food like mixture etc. Maintain good oral hygiene. Avoid harsh brushing techniques. Regards
