my daughter is 1 year 4 month old last month April 9th I was detected corona positive we can't isolate her because whole family was corona positive. she also had fever 1-2 days after that she was fine but after one month she is having cough that to only at night between 3-5 am.In day time she is fine. We went to doctor he has given grilinctus ,cetzine, and random -PD.but in one week there is no effect. not even a 1%. what should I do I tried home remedies also like honey with pepper powder. but nothing works.kindly help.
