I feel like some thing stuck in throat. I don't feel hard for swalloing. But feel something. My brother has positive in corona and he recovered without any symptoms from begining in home quarantine. I have problem like some kind of fluid flow from stomach to throat. I though it's a acid reflux and taking medicine now. Still I got something stuck in throat. If I waked up in morning it's not feel like that but after sometime I feel the same something stuck in throat. I have no symptoms of cold or running nose or cough too. I have already taken test before 25 days with my brother I got negative. But worried of that something stuck in throat. I am worried I have corona is it symptom of corona or I will get die when I sleep with breathlessness. I am so scared. Pls help me on this
