Hi I was tested covid positive at 13 th April with Ct value.17 and reported negative at 29 th April in Rt Pcr report. In this duration I don't have little bit dry cough and fever in starting two days. I start feeling dry cough issue again from 1 st may , I take medicine prescribed by doctor. 1: Azithromycin 500 mg 2: ascoril+ cough syrup 3: zac-d. I used this medicine for 5 days. Means 2-7 th May. Still I am suffering from dry cough issue. I feel this issue mostly evening except this remaining day  I feel normal.I don't have other issues like fever , breathing issue..etc. Please suggest me what should I do. Because today approx 20 days from covid negative report.
