thanks for your query, i have gone through your query. the redness and burning sensation over the tongue could be because of the depappillation and fissured tongue. these can occur secondary to nutritional deficiency. the swelling over the cheek could be because of the tooth infection resulting in abscess formation. consult a oral physician and get yourself examined to rule out the above mentioned conditions. it it is fissured tongue you should maintain the tongue hygiene and use topical analgesic, anesthetic and antifungal drugs. if it is tooth infection take a course of antibiotic and treat the tooth.
