Hi thanks for contacting HCM... You had history of fever, cough and body ache .... So you can have bronchitis or pneumonia like infection ....... You are given antibiotic course ..... Now only cough is there .... With time it will resolved ... If cough dry than dextromethorphan and if cough wet than ambroxol tablet taken .... Take one tsp honey and one tsp ginger juice ....mix them and taken daily .... Drink more water ..... Smoking and excess spicy food avoided. ... If cough more than three week than I would suggest you to go for chest x ray .... If needed , to assess severity spirometry done .... Your teeth pain could be by gingivitis like condition .... Maintain oral hygiene and antiseptic solution gargles done .... Consult physician with keeping this in mind .... Take care
