There is pain in hard palate of my mouth I have this problem from last 2 to 3 yrs. When this happens that area becomes red, my body becomes completely weak. My mouth also smells bad despite of brushing regularly and using mouth wash. Some times small peace of cough also comes out from my mouth which smells awkward in the same way my mouth smells. After taking anti biotic I get cured but again it happens regularly after 15 to 20 days . I went to dentist as well as ent specialist. They gave me a lot of different medicine's. But still I face the problem. What should I do now?
