<s>[INST] My husband bit his tongue very hard (2 different times). Now he has developed a very painful, swollen, almost tumor looking sore. It is very difficult for him to eat. Topical treatments are not working to numb the pain. What can he do to minimize the pain/discomfort & speed the healing process? [/INST] hello welocme to health care magic its better u consult some dentist those may be pre cancerous lesions.. </s>
