Hello and welcome to health care magic ! I am really concerned of your problem and try to solve the issue as soon as possible . From the info you provide , it appears that you have multiple issues like sinusitis , infection of middle ear cavity and this has encoached to your mouth too , possibly along with fungal infection in your mouth . in my clinic I usually tell people , along with treatment , with some alternative tips like , using ginger tea along with cinnamon , taking saline steam twice a day and using coconut powder for mouth bumps . Now , you can take medications for pain like Ibuprofen , naproxen etc ., use steam , avoid spicy and fatty diet . Some antibiotics like , Amxil 500 works too . I think do try these alternative methods and see your primary if the problem does not resolve . good luck . Hope I have answered your question . Please do not hesitate to ask any follow up questions if needed .
