Hi welcome to health care magic... According to my opinion you should take rest as ear pain might be from Eustachian tube swelling secondary to infection... You can have allergic or viral bronchitis like condition.. Your chest x ray and sputum cytology examination needed for further work up as three week of cough present.... If needed sputum culture can be done to isolate organism and treatment accordingly Drink more water Steam inhalation done two time a day Take turmeric powder with milk daily Investigate with CBC along with AEC count to exclude allergy... Consult physician or pulmonologist for examination and further work up
