Covid recovered, mild/dry cough persists

I was covid infected two weeks back.In CT scan report,my covads score is 4.Blood test reports are CRP is 3.1,D dimer is 300, Ldh is 464,Ferritin is 312, IL6 is 5.2, CBP-Heamoglobin is 14, CBP-Total WBC count is 6100. I haven't taken negative report, but I'm feeling ok and normal at the moment. I have recovered from fever, taste/smell senses since a week, But mild cough is not reduced yet. I'm doing steam inhalation twice a day and taking ascoril cough syrup once a day and Dextromethrophan syrup twice a day , montair LC tablet at night for 6 days(stopped after 6days), and replaced with coldact tablet at night for 3 days,followed for 10days and Cough was 50% reduced, but if I stop steam inhalation and cough syrup for one day and I can notice sense of infection at middle of chest while coughing, it's a mild/dry cough. I resumed Steam inhalation and cough syrup again. My dry cough is in control at the moment but not completely reduced,what should I do to completely reduce mild cough?
