Cough, sore throat, ear pain. With this.

I have been having mild cough sore throat for more then 2 weeks. Couldn't take medicine since was quarantine for 2 weeks. My mother was tested on 15april and on 18 she was shown covid positive. I have 1 month old baby. I and my baby were tested for covid on 20 april and the test were negative. I was tested on 31 march before baby birth that too was negative. I met an ent doc after two weeks and she has told me to do betadine gargle (5 days) and steam wid karvol ( 15 days) Gave me some acid reflux syrup. Since baby is too small don't get much time to do it. Later She gave me xycal 5mg  after pantocid 40mg. She said. I have mild ear pain so she has given calpol 650 mg. And I felt like ulcer so tess ointment. Can any doc help me with this.
