I'm really worried about my brother. About twenty days ago, he started having chest congestion and trouble breathing. We took him to a physician who gave him an x-ray, an inhaler, and Montelukast. He seemed okay at first, but then on the third day, the symptoms came back. We rushed him to the hospital and he was admitted for suspected COVID-19 because of his cough and sneezing, but all his tests came back negative, and they discharged him when his x-ray seemed fine. Now, he's feeling that breathlessness again, along with this acid-like feeling in his lungs and stomach causing chest congestion. Could this be because of anxiety? His heart rate shoots up when he feels this way. We're really struggling because there's no specialist around here since we're in a red zone. What could we do to help him? Any advice would be appreciated.

start a inhaler which was suggested to you. take tablet . pantoprazole for 3 days
