Welcome in H.C.M.
I have gone through your query regarding premature termination of antibiotic course in case of ear infection
As you said that you stopped antibiotic prior to complition of course as you were feeling much better, here I would like to say that you have taken a wrong decision because incomplete couse of antibiotic always increases the chances of-
1- Reccurence of infection.
2- emergence of resistant mutanats needs second line of antibiotics.
Now in your case weather antibiotic is neede or not and what should be line of treatment this all depends on status of disease and for this you have to consult your ENT doctor to recover well and toavoid complications.
