Name : Soma Sampath Kumar Age : 28 years Weight : 96 kgs Height : 5.7 feet Other Problem : Nothing Note : My Mom and Dad got covid and now recovered but I have tested almost 3 to 4 times Anigen test got Negative and RT PCR got Negative and CT Covid Screen got Co Rad 1 I am suffering from continuous sneezes from almost 3 months. But in beginning there in no cold but only sneezes. From past 3 weeks suffering with cold , runnynose and watering in eyes and light cough. As per one Doctor's suggestion I used Montack LC for 5 days once in the night after dinner. It was good actually when I used it but just after 2 days after completion of course its started again and now feeling itching in ears and now not using anything only taking steam once or twice a day and drinking hot water. What else in need to do to come out of this? Kindly suggest me do I need to take any other medicines or do I need to take any other precautions or do I need to take any special care.
