For the last 1 month I have been getting pain in my chin and could notice a tiny lump. Even that irritates a  nerve vessel which gets swollen inside the right cheek . It generally subsides in night hours and again triggers in day time . I consulted the Dentist , they performed xray of the molar teeth and mentioned maybe gums are affected which could be the cause and suggested a tooth cleaning . I did that but it did not provide any relaxation . This same issue was there in 2018 and I had used allergic medicines as suggested by an Internal medicine specialist and it got cured. Please suggest whom should I consult and what could be the issue behind
