<s>[INST] Since yesterday I have started getting a feel that my left cheek inside jaws have started paining with swelling&the lump growing in size it pains when pressed outside? I am a tobacco gutka user since long? Isthis related to of cancer or what should i do? [/INST] Thanks for your query, I have gone through your query.The pain and swelling can be because of the tooth or gum infection leading to periapical abscess formation. Nothing to be panic, consult a oral physician and get it evaluated. Mean while you can take a course of antibiotics like amoxicillin and metronidazole. Regarding your habit of tobacco chewing, you need a thorough examination of the oral cavity. so consult the oral physician.I hope my answer will help you, take care. </s>
