Lung infections are very common after upper respiratory tract infection (URI). And in old age(age more than 59) chances are even high. So possibility of lung infection is there in your case. Lung infection can be either1. Bronchitis2. Pneumonia both cause rapid heart rate, coughing, wheezing, nausea etc. So better to consult pulmonologist and get done1. Chest x ray2. PUT (pulmonary function test). Chest x-ray is needed to rule out pneumonia.PFT is needed to rule out bronchitis. So consult pulmonologist first and get your self diagnosed, then start treatment accordingly. </s>
