Hello and hope you are doing well.
If it's the right antibiotic, then the infection should resolve. Have a culture and sensitivity test done to find out the correct antibiotic that the infecting organism is sensitive to and taking this medication for the required amount of days may help to clear infection. Please discuss this with your doctor am sure he will provide further assistance.
Hope this helped and do keep us posted.
